We are using LoadRunner 12.53 with Windows 7 64 bit.
When executing load test, controller is crashing and I see below error in the event log. The scenario is executing 6 web services, distributed across 600 Vusers.

Tried restarting and clearing up the temp; however, I am still getting the same issue. Does anyone know if there are any patches that need to be applied.

Any input would be great.
