Issue:
When attempting to export a project from PPM to Open Workbench (OWB), some users receive the following error: Unable to start scheduler - Workbench Create Dispatch error.

However, when other users attempt to export a PPM project to OWB from the same computer while using their own Windows login, the project opens in OWB without any error. 
Cause:
The error indicates that the user does not have full access to the directory that Open Workbench and Schedule Connect are installed on. The two components are installed under Program Files (x86) by default.  
Resolution:
Grant the user read/write access to the folder where Open Workbench and Schedule Connect are currently installed. Alternatively, uninstall Open Workbench and Schedule Connect, and reinstall both on a directory that the user has full rights over, such as the C: drive.
