This is the third post in our series about 64-bit installation development in InstallShield. The previous posts are located here:
In this scenario, an application has both 32-bit and 64-bit components, and needs to be installed on both 32-bit and 64-bit Windows. This can be accomplished with two installation projects. One installation dedicated to installing the 32-bit components of the application. A second installation dedicated to installing the 64-bit components of the application. To avoid confusion, you should probably give the 32-bit and 64-bit releases different names.
You may be thinking two installation projects is more difficult to maintain than one. I agree. However, in doing research on the InstallShield forums, I have come across people whose installation situation actually work best with two projects. I can’t give you any more specific information than that. If you think this might be your scenario, you’ll have to look in the forums and look for specific posts on the topic.
Scenario 3 is the one that I have worked with the most. I’ll talk about that next and give specific details on its implementation.
