Hi,
We've recently purchased Advanced Installer Professional. Most of the things we needed work great, however we run into the following problem.
We'd like to make our software upgrade as seamless as possible:
1) Same build should be able being installed again.
2) Different builds one on to of another.
3) Different versions one on top of another.
If this requires uninstall, we'd like it being transparent for the users.
The only thing which should be forbidden in an older version on top of the newer one (exactly as it works today).
I played with various settings in the Upgrade section and tried "Automatically upgrade..." and "Allow side by side..." options, as well as custom upgrade definitions, but still wasn't able to overcome the following problems:
1) Sometimes when I rebuild the installation (self extract exe) with the same version, I get an error: "Another version of this product is already installed..." It offers a manual uninstall which is not good for us.
2) Other times, the installation seems fine, but our dlls are not being overriden (I can see this by their modification time).
Your help will be appreciated.
Thanks
