Customer reported he was unable to run PowerShell scripts from Event Broker. We tried both the PowerShell Script and PowerShell Execute activities and the error was always along the lines of "file not found".
Initially he had the script in the root of drive E:. I had him move it to E:\test but EB still couldn't find it. Then we tried drive C: and this time EB found the script and ran it correctly.
As the customer is using Win 2012 and IIS 8 there is perhaps a compatibility issue?
