I have NO idea what I did. I was using it and it worked fine. I must have cleaned something out with CCleaner in the registry and messed something up is all I can think of.
I used Revo and removed everything and started over and downloaded Sigil 8.6 64 for Windows 7 and let it install to the default folder as usual. It would not install the Microsoft Visual C++ since that was already installed of course.
When I click directly on the Sigil Icon and try to launch it I get the MSVCR120.dll error. If I try to open an epub I get various dll errors. They change from time to time.
I went back and looked in my computer and I had several instances of Microsoft Visual C++ installed so I used Control Panel and Revo and removed them all and started over again with Sigil AGAIN and let it install C++ on it's own, which it did. I did start and restart the computer in between just to make sure.
Here is the whole crash just from trying to start Sigil:

Am I going to have to format my computer just to install Sigil? I can't even remember the last time I used it so I don't have a point in time where I think I could roll my computer back to.
