Here's a catch 22 if I ever heard one. I failed OGA validation and found that it was the Viso 2003 I installed for evaluation which caused the failure. OGA stated I needed to uninstall the program in order to pass OGA validation. I went to Control Panel to remove the program and got the following rather lengthy dialog error:
"The patch package could not be opened. Verify that the package exist and that you can access it, or consult the application vendor to verify that this is a valid Windows Installer patch package."
I started getting this error after I swapped my original boot drive (which became unstable) with one I keep in my system as a clone using MaxBlast 4.
