Download Help Centers

The Help Centers provide you with comprehensive user assistance.

We recommend that you use the online versions of the Help Centers for the most recent updates available. If your organization has firewall restrictions that prevent you from using the online versions, you can save the help center files locally.

Access local help

When using the local help:

  • For some VuGen components, there is a switch to toggle between online and local mode. To change the display option, select Help > Help Center Options > Open Online or Open Locally.
  • If you are working on a full installation LoadRunner Professional machine, the Help Center Options for all components are set according to the setting in VuGen.

Note: If the online help center is unavailable at the start of a VuGen application session, the Open Online option may be disabled during the whole session with that application.
