Download help centers

Our 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.

Note: To view a help center in Internet Explorer, you need to enable Javascript (Active scripting) in your browser settings (Tools > Options > Security > Internet > Custom Level).

  • If you are working on a full installation LoadRunner machine, the Help Center Options for all components are set according to the setting in VuGen.
