I have an old version of my program: v3.0.0 and v3.0.1.

Both of these were done with ISDev7.0 which used Windows Installer 1.2

My new version, v3.1.0, is done in ISDev7.04 which uses Windows Installer 2.0

v3.1.0 is a Major Upgrade - i followed all instructions according the help files / web site knowledgebase.

On WinNT machine (NT4, 2000, XP) this works great. The old version is uninstalled and the new version is installed, when I run the setup for the new version.

On Win9x machines (98, 98SE, WinME), however, it doesn't work. It fails somewhere between "Removing files" and installing the new version.

Any clue why? How can i solve this without having use use Windows Installer 1.2?

Thanks for the KQ article. I'm going to try it this way.

Where can i find info on how to manually run the uninstall of the previous version?
