Failed to uninstall Visual Studio 2015 Preview and Visual Studio 2017 RC

Question

I installed Visual Studio 2015 Preview, when I am trying to uninstall it by rerunning vs_Enterprise.exe, in the end it gives me this:

I also installed Visual Studio 2017 RC, trying to uninstall in the same way it gives the same error message.

When I click 'Modify' from

It gives me this error:

Now both are stuck there, I can't remove them and also can't reinstall them.

I also tried the possible solutions which I can find from google, and none of these works:

1. Uninstall from control panel:

   Can't find Visual Studio 2015 Preview and Visual Studio 2017 RC in control panel's Programs and Features window

2. Run vs_enterprise.exe by using the /uninstall /force command-line:

   can't find vs_enterprise.exe from Package Cache folders, somewhere like this: "%ProgramData%\Package Cache",

3. Use VisualStudioUninstaller:

   This doesn't work either.

When you install the VS 2017 RC on the Pc that already installed the VS “15” preview, the prior previews of Visual Studio "15" must be uninstalled first, so you not need to uninstall the VS “15” preview again. During installation of Visual Studio 2017 RC, a cleaning tool will automatically be run on your machine that will detect artifacts from a prior preview installation and then remove them, you can check Frequently Asked Questions (FAQ) for Visual Studio 2017 RC.

To uninstall the VS 2017 RC and VS "15" preview edition, you can try to directly remove those 3 folders: %ProgramFiles(x86)%\Microsoft Visual Studio\VS15Preview, %ProgramFiles(x86)%\Microsoft Visual Studio\2017 and %ProgramData%\Microsoft\VisualStudio\Packages, then re-run the VS 2007 RC installer as administrator, it should display as a new installation.
