VuGen hangs when trying to create parameters

When trying to create a new parameter in VuGen, the CPU utilization for VuGen.exe goes up to 100% and stays there eventually causing VuGen to crash.

Diagnosis: The ss32x25.ocx file was not registered on the machine.

Solution

Register the ss32x25.ocx file on the VuGen machine.

1. Check if ss32x25.ocx exists in C:\WINNT\system32 or C:\windows\system32 where it is copied to during the LR/VuGen installation.

2. Check the version of the .ocx file, and confirm it is 2.5.0.20.

Note:

If the file is not present or the version is a lower one, copy it from a working LoadRunner machine, or, it can be found in the LoadRunner installation DVD, under this folder:

lrunner\MSI\setup_j\register

3. Register the ss32x25.ocx file using regsvr32.

Use the regsvr32 command to register or unregister a DLL
