Corel Closing Error

Hi,

Long story short, an engineer has just visited our site to service our Laser cutter. He has added a new colour pallete to Corel Draw, but to print to the laser cutter, you need to go to Tools, Color Management, Default settings, then next to Presets, we need to change it to "Simulate Color Management Off", but when we click this, Corel closes down straight away, without giving us chance to save the settings.

When logged in as an administrator, the file prints fine to the Laser Cutter and the presets stay as they are, without Corel crashing. If you login as anyone else though, and try changing that setting, it crashes.

This appears to be a permissions problem (as it is working fine with the administrator account), but what security settings do I need to change? or Is there something else I can do?

Unfortunately the engineer didn't have a clue, but hopefully someone here does.

Thanks.
