Citrix process is already running under a different user account

Problem

When executing a Citrix load test, the following error message displays: Citrix process is already running under a different user account. This happens when the Citrix process wfcrun32.exe is already running under a certain user account. For example: A Windows session is already used by the user A. When a load test is started, an agent logs into the same Windows session as user B. User B now attempts to start the process wfcrun32.exe, which does not work and causes the error to display in Silk Performer.

Resolution

Close the running Windows session by logging out user A before you start the load test.
