Upgrading vs. Clean install

Has anyone reported any issues with upgrading from Win XP rather than a clean
install? I think I may run into a problem with Windows Installer. I ran an
updated installer for Symantec on a test maching running a clean install of
Vista (same version as my laptop), and it installed the product just fine.
When I tried to run the installer on my laptop runnig an upgraded version of
Vista, I keep getting a message about it not being able to open the package
and to check with the application vendor to verify that it is a Window
Installer package. The vendor claims that it is, and I have verified
basically by it installing on the "clean install" machine. I am wondering if
when I upgraded, Windows Installer did not get upgraded to v.4 and is still
running at v.3x.

I did it with about 2 TB worth of files... no problem setting up Vista
Business version.

Just make sure ANYTHING the Vista Update Advisor nags about regardless
how slight you either remove or disable before you start.

And the application vendor compatible package is ?
Fyi...clean installs almost always have less problems than upgrade installs.

The latest version of Windows Installer in Vista can be verified by searching for msiexec.exe, then right click properties\version. The file resides in the system32 folder.
