Hi I'm a bit confused on the upgrade function for older versions.
I have two older versions of my software and an installer for each version built with Install Shield.
Now I would like my new installer built with ai to detect these software and uninstall them first.
One idea I found was to take the Upgrade Code Guid and add this one to the new ai project but so far I couln't find this Guid
Another idea was to use the Upgrades page in ai and find the upgrade code using the add new upgrade dialog and "installed on this machine" but the older software versions are not in the drop down menu.
Both older versions come as setup.exe. I tried to extract a msi file - but this was not working.
I would be happy on every idea what I could try to uninstall the old versions within my new ai installer.
Thanks
Maick
