Task Scheduler Error: An invalid argument was encountered

Dear all,

I've been successfully running Solidworks 2015 SP4 on Windows 10 (although I have to run it in Windows 8 compatibility mode because otherwise the open dialog crashes).  If I try to schedule a task in the scheduler, however, this gives an error: An invalid argument was encountered. This happens as-soon-as have browsed and added files in the 'task files and folders' dialog. From that point on, it doesn't matter what I try; I keep getting the error.

I've tried to run the sceduler in compatibility mode (windows 7/8), but without success.

Hope someone knows a fix.

Best regards,

Cor
