I wanted to ask if it is possible, that if I have an older version of a product I authored in InstallShield's InstallScript type project that is installed on a customer machine, then I release an updated version of that product using InstallShield Basic MSI, can I make the new version detect it and do an upgrade?
I was thinking that, from the MSI package, I could detect itand use a custom action to copy any required registry settings and files needed before calling the uninstaller for the older product, then install the new product.
Is this even possible? I am pretty new to MSI, and have made much progress recently, but we need a way to move our customers off of the old installers and get them into the new ones.
Any help is GREATLY appreciated. Thanks.
