Hi Russell,
I am not with Laminar Research; just a flight simmer.
I am no computer geek but what I read into your problem is you are having a security problem in trying to run X-Plane on a work computer.
The way I see the situation is if you are cleared to add external software to the work PC then you should discuss the problem with your IT coordinator. I am of the opinion it is not a X-Plane software problem.
Good luck
Glenn
