Remove Wix toolset from VS2010

I downloaded Wix Toolset 3.6 and it automatically installed itself in VS2010, where I was using v3.5. Now, I'm getting a compile error in my VS build and want to revert to v3.5.

How? I tried running the downloaded v3.5 toolset .msi, but nothing happens. I cannot find anything within VS2010 that lets me remove v3.6.

    Try to uninstall 3.6 from add/remove programs.

    I was able to uninstall v3.6, but no able to install v3.5. When I run Wix35.msi (after downloading it from and saving it in my downloads folder), I get a 'Open File - Security Warning' dialog and prompt 'The publisher could not be verified. Are you sure you want to run this software?'.

    I press 'Run', then I get a 'View Downloads - Windows Internet Explorer' dialog with Wix35.msi displayed and a prompt 'Do you want to run or save this program?'

    Why? I already saved the program.

    So, I press 'Run' (again) and I get another message (same dialog window), "The program's publisher couldn't be verified. Are you sure you want to run the program?"

    First, I'm surprised MicroSoft didn't sign this file. But, I press 'Run', a window flashes on the screen too quick to read and I'm back to the first prompt in the 'View Downloads - Windows Internet Explorer' dialog. This sequence repeats over and over and the application is never installed.

    Any ideas?

    anybody can sign their own code, including yourself; but in order for that signature to be trusted by wide public, it has to come from recognized trust authority, where it usually costs several hundred dollars. For that reason, you usually won't find it in open-source projects like Wix.

    If you trust the publisher of the program you are going to install, then it's your own judgment, based on what you see yourself; if it's signed, it means that you trust the judgment of the signing authority, which you usually don't even know who it is, and who signed it solely basing on the payment by the author. So it's your decision who to trust.

    Returning to the problem in hand, I would save the file into a folder, and run it from there.
