VSCommands didn't work for me and caused a problem when I installed Visual Studio 2010 aside of Visual Studio 2012.
After some experimentations I found the trick:
Go to HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers
and add an entry with the name "C:\Program Files (x86)\Common Files\Microsoft Shared\MSEnv\VSLauncher.exe"
and the value "RUNASADMIN"
.
This should solve your issue. I've also blogged about that.
