Can’t install some software packages

I am running into a situation where even logged into my local Windows 2000 Pro machine as the Administrator, I can not install some software packages (ArcServe Manager and Visio 2000 Enterprise are the 2 that I am having the most problems with)

The install for the ArcServe Manager comes back and says that the Admin has set policies to prevent this install.

The Visio install states that it needs to update some windows components which it seems to do, then asks me to restart. After restarting and trying to run the install again, it tells me that I need to update the same windows components again.

The problems seem to have started after SP3 for Windows 2000 was installed as both of these apps worked fine with SP2.

Any assistance would be appreciated.
