I know a lot was tried in this thread, but if greymagic doesn't load it's because:
* You're missing the Visual Studio 2015 Update 1 x86: https://www.microsoft.com/en-us/download/details.aspx?id=49984
* AV/FW issue where it's blocking the file or quarantining it.
* Some other tool that limits directory access or the like is interfering.
Please make sure you got Update 1 of the Vsiaul Studio x86 runtime (and make sure you run the correct file you actually downloaded in case your downloads folder has other versions already in it)
