There is a KB article which covers locating and reviewing the Installer
Logs that are created both when a program is installed, and when the
installer is run to repair. You can find it on the web at
http://support.microsoft.com/default.aspx?scid=kb;EN-US;826511. If you
find errors with specific error code numbers that are not mentioned in that
article, you can also try seeking more detailed steps or suggestions by
searching on those codes.
By the way - if you installed the Visio 2007 trial as a replacement for the
Visio 2003 full install, it might be a good idea to unload the 2007 Trial
first, then run a full repair on Visio 2003.
Also - do you run any versions of Office software which is older (such as
an older version of Access or Publisher) alongside your Office 2003 / Visio
2003 installs? Since there are shared components that might be involved,
it's possible that what you are seeing is normal behavior, with Visio
re-registering the components of Office to itself on launch.
