The scheduling service will start, but after about 60 seconds it shuts back down. Looking at the Windows event log using the Event Viewer reveals:
Application: Telerik.TestStudio.ExecutionManagerService.exe Framework Version: v4.0.30319 Description: The process was terminated due to an unhandled exception. Exception Info: System.IO.DirectoryNotFoundException
Such behavior could be caused by unfinished scheduled jobs located in the job storage folder. The solution is to manually delete these files from:
If the Scheduling Service is running as a service on a 32 bit machine:
If the Scheduling Service is running as a service on a 64 bit machine:
If the Scheduling Service is running as a user:
Then restart the Telerik Scheduling and Storage services as described here.
If this still does not resolve the issue, there is a possibility the scheduling configuration file Telerik.TestStudio.Scheduling.Client.exe.config is corrupted. Find it in the folder C:\ProgramData\Telerik\Configs and delete it. Once Test Studio is restarted the file will be generated with default configurations.
