I am using the WiX installer to install an application, and I need to set an environment variable to the CommonAppDataFolder location for the purposes of a temporary area to store files. This typically points to C:\Documents and Settings\All Users\Application Data. The problem is that the application cannot recognize long file names. Is there any way to force the use of a short name (8.3 Format)?

I’m also open to other suggestions as well. (The option to use long file names does not exist, unfortunately.)

Thanks

    Quickly perusing the WiX documentation I didn’t see anything obvious. You could write a CustomAction that calls GetShortPathName() and have it set a Property via MsiSetProperty().
