I am looking at using Installshield LE for Visual Studio, but have a question.
When I come up with an update to my application, I would like to offer it to my customers. I would like for them to be able to install it without having to uninstall the previous version. Is this possible with Installshield LE for Visual Studio?
When the older version is already installed and when you try to install a new version, you might get an error stating-
"Another version of this product is already installed. Installation of this version cannot continue. To configure or remove the existing version of this product, use Add/Remove Programs on the Control Panel."
To avoid this and to automatically uninstall and remove previous versions of your applications, please try the following:
-> In Solution Explorer go to "General Information" page -> Increase the Product Version -> Generate a new Product Code -> Make sure that ALLUSERS property has the same value as in the old package -> Go to "Upgrade Paths" page and add the old MSI -> Build and install your new version
When running this new package it should automatically detect and remove older versions.
