Problems with Sandbox and launchers.

I can’t find this on a search and I’ve looked through the forums and so far no answer. I’m having trouble with getting SOnic RIders to run on a re-built XP machine with version 7 “free” running.

The symptoms are:
Run the launcher - either directly or through autorun.
Click Play
Error dialog appears saying “You can only start this game from the launcher” - which I just have.
It doesn’t make any difference if I add the launcher and/or the exe to the exclusion list it still happens. The only time it doesn’t happen is if I disable file system shield.

Any thoughts please

In the file shield settings set auto sandbox to ask
