I just installed this OS fresh - everything is working, got MS Office installed, firefox, etc.

Just purchased and downloaded ZASS. I double-clicked the install file, and a window titled Use Account Control asks "Do you want to allow the following program to make changes to the computer" - I click Yes.

Then a windows entitled Error pops up which says:

Could not load the DLL Library.
C:\Users\Sindyr\AppData\Local\Temp\121108214008\vs util.dll
The specified module could not be found.

The only button to be hit is OK, which exits (fails out of) the installation process.

How can I installed this paid program correctly?

Operating System:Windows Vista Ultimate
