What level of user account privileges do I need to run SilkTest scripts on an Execution Server?
You will need to ensure that all testers who are running SilkTest scripts on your execution servers are logged in with Administrator privileges. This has always been a requirement for running SilkTest as it is able to make calls at the system level e.g. to read and write to the Registry.
If executing SilkTest scripts is not a requirement of the current user then a lower level of access can be given but the exact access rights will then depend on what your user is required to do within Test Manager.
