Uninstalling the Office 15 Click-to-Run Extensibility component

So I was trying to install some 64-bit Office products on my computer and saw the following error message. There seemed to be a 32-bit version of the Office 15 Click-to-Run Extensibility Component installed on my computer.


The Click-to-Run Extensibility Component does seamless transparent upgrades of the Office product in the back end. So there were good reasons for not removing it. But if it prevented me for installing additional features because it was 32-bit then it was time for it to go.

IMPORTANT: If you have 32-bit version of Office installed, DO NOT remove the Click-to-Run components. Office applications may stop working altogether. I was able to do this because my version of Office installation was 64-bit and this item was unrelated.

Problem was, I couldn’t find this program in the programs list in Control Panel. So I was wondering how to remove it. After digging through the registry for the installer (or uninstaller), I found the key related to it and it showed where the MSI was that installs it.


So went to that location, right-clicked on c2rint.msi and selected Uninstall. Confirmed on the Installer dialog.


That did the trick. The product was removed and so was the corresponding key in the registry. There were other products as you can see in the registry that were Click-to-Run related but since the 64-bit installer didn’t complain about these, I left them alone.


I was able to proceed with the installation of the 64-bit Office products I wanted. It may have been a remnant from an old 32-bit install. It is believed (but I can’t vouch for this) that the 32-bit version gets installed when you have preview versions of Office installed. In any case, there is a way to get it out if required. Now to see if I regret removing it eventually.

    Thankyou! This was a wonderfully written document. I was desperately trying to install a trial of Project I needed for some work and nothing on the microsoft website helped.

    Mind you, this only worked on one of my computers, but thats all that I needed and it is the only thing that worked:)

    Have an awesome day and I just wanted to say how much we, people of the internet appriciate articles like this!

    I got lost at the point where you couldn’t find it in control panel and had to dig through your registry. Could you please explain in greater detail how you did that?

    • October 28, 2013 at 1:07 PM

      Hi Jo. I’m afraid this is not going to be a very satisfactory response. If there is an (un)installer available for anything that you installed on Windows, it is typically recorded in the registry. When I am unable to locate it through Control Panel which should typically hold a handle to the installers, my fall back to go look in the registry. Mucking through the registry is typically not a good idea if you are not an advanced user but if you spend long enough doing it, you’ll find that for products installed on Windows, you’ll find the installer used under HKCR\Installer. Some searching will be required to locate key containing the product you want and then the SourceList key will lead you to the installer used. There is obviously the need to know where to go to look in the first place which is why I even had to write this post. Because that is not obvious and is known to people who have learnt the hard way before.

        November 29, 2013 at 5:07 PM

        First off, thank you for this article for it is exactly what I am looking for but I am encountering a problem: I found the registry in my system but was unable to open it because of my inability to find a program able to support it. how did you open the registry? With which program did you open it? Did you even have trouble opening it?

      • November 29, 2013 at 8:08 PM

        Hi Parker. Typically, you should be able to bring up the “Run” dialog (Windows + R) and type regedit.exe to launch the registry editor. You need to be logged in as an administrator on the machine where you are doing this to have the registry editor function.

        August 11, 2014 at 11:23 AM

        If you needed Lennanki to be a little more explicit or break it down more for you when you go to regedit, do not try to open the file, under the data column in the window pane to the right under the data column hover your mouse over the file location to get the full location address go to your file folder and navigate to the location. Then right click and choose uninstall. on the c2rint.msi file. Your file location may be different, but mines was C:\Program Files\Microsoft Office 15\Root\Integration. I hope this was helpful.

      • Joyce
        January 16, 2015 at 2:41 PM

        Thanks for the link, Darcell – your path worked for me. In the registry there was no “uninstall”, just delete.

      • January 16, 2015 at 3:00 PM

        The “uninstall” option is not available in the registry. What you get from the key in the registry is the location of the installer. When you locate it, if you went and found that file and right-clicked on it, you should find the uninstall option.

      Sorry. Didn´t look on the bottom. Found it. The issue now is that I already deleted it but the error remains 😦

      • November 1, 2013 at 3:03 PM

        Laura, Sorry to hear that you’re still having the problem. Did you delete the key directly from the registry or did you try uninstalling using the MSI? Also I would check the error in detail to ensure that it is still referring to the Click-to-run extensibility component. There may be other 32 bit components that are blocking your 64 bit installation.

      Thanks for this! I did the un-install route, but that didn’t work. deleting the whole 00005109… in RegEdit did the trick.

    what if deleted it from registry and not unistalled it ? what would i do now ?

    • January 20, 2014 at 9:56 PM

      I would imagine that the things that the Click-to-Run component obstructs during installation should go through fine once the registry entry is removed. However, in the interest of cleanly removing it, uninstallation should be the way to go. Changing things directly within the registry should be a last resort.

    Brilliant article. I get to the registry and then right click but the only option I get is “New”.

    How do I access the uninstall option?

    There must be so many people with this issue – it’s strange MS haven’t provided an auto fix when installing 64.

    • January 26, 2014 at 10:53 AM

      Zach. Thank you. I only went to the registry to locate the installer/uninstaller MSI. There isn’t an option in the registry itself to uninstall. Once you locate the uninstaller, you will need to navigate to that location, right-click on the actual MSI file and select “Uninstall”. Hope this helps.

  15. Neil
    January 27, 2014 at 10:37 PM

    I took the uninstall option by right clicking the msi file(s) themselves, uninstall seemed to work but upon subsequent failure to load visio or project, I re searched for the msi’s and they were still there, so I renamed them to -old.
    however still cant install the other products.
    Of course I rebooted in between.

    Any further suggestions anyone ????

    • April 25, 2014 at 1:03 PM

      Ntau, You shouldn’t have to go to the registry if the .msi through which you can uninstall exists in the same location as where I found it on my machine. Can you check if it is there? If not, you may need to check within your registry. The registry editor can be accessed by typing “regedit” in the Run menu or at the command prompt. If you are running Windows 7 or later, you should even just be able to search “regedit” through the start menu.

    • September 7, 2014 at 8:53 PM

      If you look at the second screenshot posted, you will notice the registry holds a key indicating the location of the installer on the disk. Once that is ascertained, all you need to do is navigate to that location in File Explorer, right click on the installer and select Uninstall.

    Thats great and it worked fine, excpet that I am not able to see my Office applications that were installed previously to the 64 bit install (and de-install of the MS project 2013). Have tried reinstalling the Office Apps, but no luck, any suggestions ?

    • September 10, 2014 at 3:13 PM

      If you had a 64-bit version of Click-to-Run extensibility component linked to 64-bit Office products, it should not have been uninstalled. In my case, as I state in the post, I had an orphan 32-bit version of the click-to-run extensibility component that got added with some prior installation of 32-bit Office products and didn’t go away when those were uninstalled. This article speaks to how to remove such orphaned components.

    • October 22, 2014 at 3:41 PM

      It is not recommended to muck around with the registry if you are not very familiar with it. However, to access it, you can access the “Run” dialog in Windows (shortcut: Windows Key + R) and type “regedit” and hit Enter.

    Ran into this problem as well, ran uninstall on the directed MSI, but the program refused to install saying the program was still there even after a reboot. I had to backup and then delete that entire registry entry manually before it would complete the instal. In my case the Visio Pro 2013 64bit.

    March 2, 2015 at 4:02 PM

    I’m actually in a bit of a bind here. I’m not at all familiar with or experienced with what belongs and what’s necessary in the registry. Therefore, I didn’t really see it as a viable option to access when I realized that my problem resided within the registry. Long story short, I’m currently running Windows 8.1 and utilize a 64-bit processor. The current Microsoft Office I have installed is 32-bit. I recently tried to install the Visio Pro 2013 Trial onto my laptop, but I didn’t know it had to be the same bit-version as Office. So, my first attempt lead to a failure as I had first downloaded the x64 set-up. The set-up failed, and NOTHING got installed. I then again downloaded the correct bit-version of the trial, and the install took place. However, it didn’t go all the way and told me that I couldn’t use the product key because of a recent trial already being installed, error 25004. I tried 2 more times after that, and after all attempts, the bootstrapper program failed. So now, I’m tired, and desperate. I’m even considering just factory resetting my laptop, just so I can get the trial to install. However, I’d like it if I didn’t have to go through all that, so I’m liking what I see so far, but if someone could give me a very detailed instruction set as to how I can perform this miracle that would allow me to install the trial successfully, that’d be great. On a side-note, the trial and or Visio does not appear in my programs list. If you need any information from me, I’ll try to reply to you as soon as possible. I really need this to work as I only have my Laptop and smart phone. I would go to my college and access it there for free, but that’s a 40-min commute and I don’t really have all the time in the world. Thank You for your time and for this post!

      If you check the screenshots I posted, you will see the specific key and the location in the tree where you will find it. It will indicate to you, where in the file system, the uninstaller is stored. Navigate to this location using Explorer, right click on the installer (.msi) file and choose “Uninstall”. Hope this helps.

    Thanks just what I needed

    You should leave out the part about finding it in the registry and just supply the path directly to the C2RInt.msi file. This will make the article less confusing for some people and faster to search for others. Otherwise, great article, fixed my issue immediately and I sir thank you for saving my time!

      Glad it helped you. I just didn’t want to assume that the installer file is always the same and is placed in the same location as on my computer. The way to make sure people are able to locate it correctly was to lead them to their own registry setting. I agree that it may be confusing to some, though.

    Perfect! Windows 10 installed the 32bit CtR for some reason and I couldn’t for the life of me get a x64bit version of Lync to install!

    Thanks again!

      i also deletet the C2RInt.msi file

        Hi. If you look at my notes above, it says that you need to right-click on the C2RInt.msi file and select “Uninstall”. This will remove the actual extensibility component. What you may have done, is deleted the entries in the registry relating to it and the installer file for it. This is not removing the Click-to-run extensibility component itself. Can you see if you can restore your installer file (C2RInt.msi)? If you can, you may still be able to uninstall as opposed to delete.

    This worked great, had trouble installing ms visio 2013 trial. Gotta love how Microsoft breaks the installation of their own products.

    I am using Microsoft Office Starter 2010 and have the similar error message with clikt to run, when I try to install MS Project. Is it possible to fix my problem using your method, cause I can’t find similar file in Registry Editor?

    Thank you in advance

    Thank you for this post! I wasn’t going to be able to find that stupid MSI on my own for quite a while, I don’t think.

    I couldn’t use fixit as it would uninstall office 2010 too.

    Perfect solution. I would only add that the original c2rint.ms file does NOT get erased, but MS Office 15 does not use it any more, and also that the right-click gives you the option of re-installing/re-activating it in MS Office 15, if you ever change your mind.

  106. April 1, 2016 at 5:47 PM

    Thank you so much. First hit on Google, 2 minutes and problem solved!

    Lenny – please take a look at my related problem at


    My problem is: “Office 16 Click-to-Run Extensibility Component could not modify 137 protected registry keys during installation of Office 365”

    Please post there if you have any thoughts. Many thanks.

    Where did the Click-to-Run component come from, initially? Is it installed by the Windows operating system (mine is Win7 Pro) or was it installed by the Office 15 trial version that came with my PC?

    Lenny – you wrote originally “After digging through the registry for the installer (or uninstaller), I found the key related to it “. How did you dig? HOw did you know what to dig for??
    Since my issue is slightly different — I cannot get rid of 70 Β± registry entries from my initial and wrongful installation of O365 Home 32-bit — my issue won’t be solved by right-clicking and uninstalling c2rint.msi. I don’t think I even have c2rint.msi.
    Your philosophy on figuring out what to look for in the registry might help me.
