I know this is not "standard" but is it possible to use IntallShield Express to install multiple versions of the application? We have a need to have two instances of our app installed in different locations on the same box. It looks like you have to uninstall the first version in order to install the second. I have not seen anything in the designer that allows this.

I have a workaround in that I can change the Product Code value and use two different Setup files. It's not they way I would prefer, so if anyone knows another way...
