Hi,
I have the following scenario, on installation the installer creates a shared folder with a name that based on a file that exists on the pc (the file comes beside the installer on "First time installation"), but not part of the installer.
On upgrade that file is not necessarily exists and thus the installer cannot assign name to the shared folder in the same way, In this case I want to be able to keep the previous share folder name.
To achieve what you want you can go in the "Install Parameters" page, create a new property (i.e. SHARE_NAME) and check the "Set persistent property" option for it. Then store the name of your file into this property and use it as the name for your shared folder. This property will be preserved during the upgrade, so you can use it even if the file will not exist anymore.
Let me know if this helped, otherwise give me more details about your scenario.
