I think this is a Win7 problem, because I got it to work on XP and I haven't on 7. Windows 7 Pro (32 bit) SyncToy downloaded from MS (32 bit) I configured it the same as I had it on the XP system, created folder pairs and ran them from the SyncToy GUI. I added a scheduled task which I think is the same as I have it on the XP, subject to the different interface. When I try to run it the log says: Task triggered by user Task Engine received message to start task Task Started Action started Action failed to start ... Launch Failure ... addition information is 2147942667. Action start failed ... Run Failure Any ideas? Including what extra diagnostics I could collect.
