I want to use a Windows Scheduled Task to run a Multi Test Manager batch because MTM is usefull for its overview over the QuickTest Pro test results.

I've copied a VBScript from the Multi Test Manager 8.2.4 Readme. In this script I add 30 test scripts with this method:
oMTM.AddTestScript "C:\Program Files\...."

But when trying to run the VBS script, I get the message that this method is not supported.

Has anybody got an idea how to use VBScript and MultiTestManager together?
