Long story short, I am trying to install MS Visual Studio 2015 isolated shell (en-US), as is needed for another application.
That installation does not go anywhere, as nothing happens except the logo showing up on the screen for about 5-20 seconds and then it disappears.
I did try uninstaller, and forced uninstall...same thing...
From the Control Panel I can see that "MS Visual Studio 2015 isolated shell" is present and can't uninstall it (no uninstall option). After clicking on the 'change' button...same thing as mentioned before (logo pops up ...5-20sec...logo disappears)
I grabbed the dd_vs_isoshell_nnn.log from the collect tool and here are the bottom several lines :

I googled this error but nothing.
Ahhh, I found the solution by myself. Now writing reply just in case someone hits the similar problem.
Not sure if needed by I re-registered penimc.dll. After this I got step further in uninstalling Isolated Shell 2015...after logo I got big black rectangle ...but nothing on it. As related framework for the penimc.dll was version 3.0, I found out that I don't have .NET 3.0.
I have enabled .NET 3.5 (including 3.0 and 2.0) 'windows features' and let windows downloaded all the necessary files.
After that voila!

I had the same issue not able to uninstall the visual studio 2015 shell (isolated). I tried all I could but not seeing the option to uninstall then I decided to click on modify, ran as adm then I found uninstall option. Done!
