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.

The following English packages are available for download. Download the packages that you require. For details, see Access local help.

Access local help

The following procedure describes how to install and access the help on the local machine.

The help packages required for each product, and the location to install them, are described in Local help packages.

To install and access local help:

  1. Download the relevant help packages to the machine where the product is installed.

  2. Check that the VuGen root installation folder contains a help folder. For example:

    C:\Program Files (x86)\OpenText\Virtual User Generator\help

    If the help folder does not exist, add it.

  3. Unzip each package into the appropriate folder. For the context-sensitive help to function, the format of the content must be kept as-is, and the content must be placed directly in the specified folder for that package (not in a subfolder).

  4. For some VuGen components, there is a switch to toggle between online and local mode. To use the local help, select Help > Help Center Options > Open Locally.

    To test that the local help is working, in the product Help menu, select VuGen Help Center. The Help Center should open displaying a local path, not online.
