I upgraded my controller and I am seeing this error when running tests, "RESERR: 154 - Wrong BEX file format, the specified bex file is no valid executable file"
When you upgrade the MMC to a new version of the software e.g. from SP6.0 to SP6.0.1, it is always advisable to upgrade the agent machines to the same version as the SilkPerformer controller before running tests.
The full error displayed in the monitor pane is
VUser-Profile1_XX AgentName 0 00:00:00 Process Exit *** Virtual user container error *** RESERR: 154 - Wrong BEX file format, the specified bex file is no valid executable file
Upgrading the agents to the same version as the controller should resolve this error. You can check the agent versions in the agent pool using
SETTINGS | SYSTEM | WORKBENCH | Agent Pool Tab
or if you have a project open, right click the agent node in the Project Pane and select "Edit Agents"
The agent version should match the build number for the SP Controller when you view HELP | ABOUT
