If I install Visio 2002 first, using the Visio 2000 installer selection in the setup dialog, it installs and works well with basic testing. But then, if I try to install Project 2000, the installer hangs on the first installer dialog.
If I try to install Visio after Project 2000, the installation hangs on the first dialog trying to update system components. It also only installs with the winxp setting.
As I get time, I'll try more tests. RIght now project is more important than visio.
