That error involves you OS and probably is beyond most users here to answer.
You will also have to provide a lot more information since we have no idea about what computer, OS, program, and action you are trying to perform. It might also involve what other programs you have running at the time of the problem.
I would start with restarting by my system and then only start Acrobat and redo the action.
Can you create this issue on another system?
