We have a product "MyProduct Basic" that people install.
We create updates for the product and just change the version number in InstallShield, When the setup program is run, if it detects it's installed, it upgrades it. If not, it performs the full installation. Works great!
We created a new Product Configuration with a new name (e.g MyProduct Pro). We want that setup to be similar to the upgrade and the Basic version if it's already installed. Because the product name changed, that doesn't happen even though I have it using the same product GUID (or not). Neither works..
Is there a way to update the existing installation and change the name so it replaces the existing program on disk and in the Windows Control Panel Add/Remove Programs list?
Without that, we are forced to tell the user:
1. Uninstall the existing version and install the new one, or 2. Have our setup program keep the old program name (so Basic stays forever) which would confuse people if they go to the control panel list since the thought they own the Pro version. For new installations, it would say Basic when it should be Pro, so that's unacceptable.
Not sure what I'm missing to handle this. Thanks in advance. .
