While installing Visual Studio 2012 in Windows 7 64-bit, the computer restarted (power failure), and after the install the folder "d:\Program Files (x86)\Microsoft Visual Studio 11.0" was gone. Now every time I run the installer, it starts installing and 5 seconds later I get the following message:
Setup Engine
Access Denied
Does anyone know how to clean everything (all directories and registry) so I can start over from the beginning?
