Hi all,
Is there a way to determine whether an application that exists in the "Add/Remove application list"?
We are planning to send out a new version of our application. When the user installs the new one I'd like to find out if an older version was installed. If an older version was found, our upgrade wizard would convert the data etc. in the process. Our application was installed using installShield expression version and it has a unique product id. The user was given the option to install the application wherever he or she wanted, therefore looking for the installation path would not be an accurate way to determine the existence of a previous installation. The conversion will take place when they launch the new application, not the new setup program.
