Garee,

UAC is important for security purposes.  But to say MS completely reworked UAC is preposterous.  It's still there in Windows 7 because it's needed.  But I'm going to argue about that point because it's off subject.

Please show me in the install documentation or anywhere in any documentation for Poser 8 where the developer advises you to turn off UAC before you install.  They don't.  As a matter of fact, they state just the opposite.  They have numerous install options several of which mention that if you are a Vista user with UAC on, this is the best option....and that is the default install option.  However there are several other options for installation which they clearly did not test and they give the user no instructions regarding UAC at all.

This isn't about your problems with Microsoft.  This is about poor quality testing of a very nice, welcome update to Poser.
