Vuser Errors

This section describes troubleshooting for the following Vuser errors:

Initialization Problems - Online Process Failed to Initialize

Failed to create Online: 'process'

The online process has not been initialized.

Troubleshooting

Check that the Controller COM objects are registered in the Registry Editor: HKEY_LOCAL_MACHINE\SOFTWARE\Mercury Interactive\LoadRunner\CurrentVersion.
If they are not registered, run register_controller.bat from the <LoadRunner installation>\bin directory to register the COM objects.

Tip: To locate the installation directory, in Windows, click Start > Run and type wlrun.ini in the Open box to open the wlrun.ini file. Go to the [ProductEnv] section of the file and note the LoadRunner installation directory in the line M_ROOT=.
If this fails to solve the problem, contact customer support and provide them with an explanation of the problem, and the error message returned.
