I have a project with a major change that I want to be able to install alongside previous versions.
Each major version has it's own install folder and an different folder name in the registry.
Let's call them version A and Version B.
Version A installed: installing version B will not overwrite version A.
If I install a newer version B, it will overwrite the earlier version B but not the currently installed Version A.
If I install a newer version A, it will overwrite the earlier version A but not the currently installed Version B.
'Allow side-by-side installs of different product version' is NOT the solution here.
Can I accomplish this by simply changing the upgrade code of version B to differ from Version A?
Any pitfalls I should look for?
Thanks!
