Here is my story:
I at one time installed Visual Studio 2015 Community Edition. I then uninstalled it, but the uninstall went badly somehow.
Weeks or months later, I saw the software lingering in the Programs and Features area where you can modify or uninstall programs.
So, I tried to uninstall it again and could not because the package was missing from the Package Cache folder.
Now, I don’t claim to understand how all this works and why it just hung when I tried to both uninstall and repair it. All I know is that sometimes I would get a dialog box during the uninstall prompting me to browse for the package that apparently was missing.
I did a lot of research and tried a lot of different things. Nothing worked for me. Without that package, I felt doomed…. until I came across this article.
I hope this help someone else as it did for me.
Follow the section under:
