I was wondering if the following is possible. We have an existing product that is an add on to our main product. Now, a new version of our main product is out so I would like to set up the add on installer so that it looks in the user's registry to see if the newest version exists and if so, install there by default. But if user only has the older newer version, then I want to install to their older version by default. Basically I want the user to see the proper "Install To" folder based on which version of our main product is installed on their system.
The main program (both the previous and current versions) writes a registry entry telling of its existence, and I know how to create registry variables in Setup Factory. The part I can't figure out is how to use one variable based on it's existence or the 2nd variable if the 1st doesn't exist.
BTW, we are using Setup Factory 5. Can this be done in v5? If not, what about in the newest version?
