I need to change the default install directory name depending on a search for previous installations (allowing side by side installation) to have the current version appended to the [INSTALLDIR] directory. I had been using a custom action in a WiX installer to do this, but the properties set up in the InstallShield msi dont seem to allow me to use the same method.
If nothing else, you should be able to use a set-directory custom action to change INSTALLDIR to whatever you want, based on [ProductVersion] or [InstanceId] or [MY_SEARCH_PROP] or what-have-you...
Thanks for the reply, I had tried to do this, but was jumping in a bit early, but saw in the install logs that the property was available after cost intialise, so changing INSTALLDIR after that works.
