The software won't open. Help!

Problem: It says “Interprocess exception (boost: 7, native: 2): The system cannot find the file specified.” What can I do about it?

ActivePresenter Version: I think it’s 6.1.6

OS: Windows

Notes:

Please restart your computer and try to record again to see if it helps.

Regards,

I always had to do that when that happens, what others things I can I do?
