All of our Windows 7 computers have a task that runs daily and calls a
simple batch file to backup the pc. Sometime in the past task scheduler
started crashing when trying to run that task. Actually in
troubleshooting we discovered it would crash when we scheduled it to run
any .cmd file even with highest privileges.

After seeing an error related to NIPPLIB.DLL we uninstalled the iPrint
v5.9.0.0 client from the workstation and task scheduler could run the
batch files again. Once we reinstall iPrint, task scheduler crashes
again when trying to run the batch file.

anyone else seen this happen?

below is the error from NIPPLIB.DLL in the windows application log
