What is an Offline Certificate?

You can use the GenRocket Runtime while connected to a secure network or offline.

To use GenRocket Runtime offline, you will need to add an offline certificate to your .genrocket folder in your home directory.

Note: You do not need to use an offline certificate if you are connected to the Internet in a non-secure/corporate environment.

How Does the Offline Certificate Work?

  • Each offline certificate is specific to a GenRocket Organization.
  • Each offline certificate lasts for 24 hours.
  • After 24 hours you will need to download a new offline certificate and place it in your .genrocket directory.

Note: If you are a member of two GenRocket organizations you will need to download an offline certificate for each organization.

How to Download the Offline Certificate

Step 1 – Confirm resource.home.directory Value

  • Within the Resources Pane, confirm you have added a value to the resource.home.directory.
  • This is required to use an offline license and should match the System Home Directory path (usually C:\Users\User Name).
  • If one has not been assigned, click on the Edit (Pencil) icon.
  • Enter the directory path as the value and click Save.

    Note: This will need to match your system home directory path (usually C:\Users\User Name).

Step 2 – Download the Offline Certificate

  • Within the Resources Pane, expand the Download drop-down menu and select Download Offline Certificate.
  • This file will be named like this: GR#######Certificate.grc. (The # symbol represents numbers within the file name.)

Step 3 – Place the Offline Certificate into your .genrocket Folder

  • Navigate to the directory where the offline certificate was downloaded. This will typically be your Downloads folder.
  • Right click on the file and choose Cut or Copy.
  • Navigate to and open your .genrocket folder. It can be found in your home directory (usually C:/Users/User Name).
  • Right click and paste the certificate file into this directory.
  • The fill will appear as shown below in the .genrocket folder:

Step 4 – Verify offline certificate is working

  • Disconnect from the Internet on your local machine.
  • Open a CMD or Terminal Window and change the directory to the directory path of the Scenario.
  • Run the GenRocket Scenario using the command below.

    genrocket -r ScenarioName.grs


  • If the Scenario runs successfully, your certificate is set up correctly (See image below).


Error – Unable to validate license

The following error will appear when the resource.home.directory does not match the system home directory.

To fix this issue, complete these steps:

  1. Update the Resource Home Directory (Step 1) to match the System Home Directory path.
  2. Download the Offline Certificate again.
  3. Repeat Step 3 and 4 above.
