When I install Server 2008 R2 I have came across a weird problem that will prevent me from running any MSI installation program even though I am an administrator on the box.
The system administrator has set policies to prevent this installation
Of course, I haven't set any policies to prevent this but I found the following registry key which will override this setting. Apparently by default the policy with R2 is to disable all installs of MSI's - fairly draconian but better than the default I guess:
HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows\Installer
REG_DWORD
DisableMSI set to 0
