Hello Uwe Leers ,

Are you referring to MultiTerm 2007 or 2017?

Perhaps you could post the full error stack 

Such an error I think is normally related to permissions issues/corrupted files and or incompatible Operating System,

so it would be good if you could explain exactly when the problem arises.

The more detail you can provide, the better.
