SAND: Raiders of Sophie BattlEye launch error fixed after a reboot

The Steam version of SAND: Raiders of Sophie failed to launch with Unexpected error occurred.

In the end, after setting Sand_BE.exe to run as administrator and rebooting the PC, it started launching from Steam. The reboot seems to have been the trigger, so I still do not know whether that setting alone fixed it.

This was the dialog I was seeing.

Before that, I tried Steam file verification, moving the install from the E drive to the C drive (the drive with the OS installed), and reinstalling BattlEye. At each point, the same error still appeared.

The last thing I changed was Sand_BE.exe in the game folder.

I enabled Properties → Compatibility → Run this program as an administrator, then rebooted the PC.

After that reboot, SAND: Raiders of Sophie started launching from Steam.

When I have time, I will move the install location back to the E drive and check whether it still launches.
