We are looking to change our installer from Wise for Windows Installer 3 to Advanced Installer. However, we are doing this for a maintenance release rather than a major release.
Can we do an upgrade from our old Wise installation in Advanced Installer? I would think that one step would be to change the upgrade code in the .aip file to match our old upgrade code, while keeping the new product code. Should this work? Or would the very different component structures between the two installers be likely to cause us problems?
For the future we would likely create patches for our maintenance releases, but that is not an option here.
Our evaluation is going great. Keep up the excellent work!
Thanks,
Michael
