Install via RDP...

I don't know if you have ever tried installing stuff via RDP and got the error 'You must be logged on as an Administrator blah blah' even though you actually are logged on with an Administrative account... here is how you fix that:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\policies\Microsoft\windows\installer]
"EnableAdminTSRemote"=dword:00000001

Go forth, and install...
