Has anyone else experienced this?

I have successfully deployed Mimiostudio 9.14 via GPO to machines running Windows 7 Enterprise, but I'm randomly having some teachers' machines appear that it is removing itself. The shortcuts change to a generic icon, Mimio is still in add/remove programs and Program Files (although much of the content is missing - ~6800 files vs. ~7000).

I'm currently in contact with Mimio Tech Support to troubleshoot the issue, but I was curious if anyone else has had this happen and found a solution, or might have some ideas.
