Product Key Registration

As with most software programs, all Varigence applications (BimlExpress, BimlStudio, and BimlFlex) require unique product keys to confirm usership and activate paid features. Product keys for BimlExpress (the free Visual Studio add-in), as well as trial key(s) for BimlStudio, can be requested online. Non-trial product keys will be provided to users via confirmation email subsequent to having purchased a BimlStudio or BimlFlex license or subscription through the Varigence store.

Issue

Some machines—whether they lack an internet connection for security purposes or operate behind firewall restrictions—may be unable to validate a product key through traditional online activation.

In these situations, Varigence provides offline (machine-locked) product keys, which require a unique Machine Code from the computer that will be running BimlExpress, BimlStudio, or BimlFlex.

Resolution

To generate an offline key, you must first copy the Machine Code from the target machine. The steps differ depending on the product.

For BimlExpress 2026 and newer (VS Code)​

  1. In VSC Code, click the BimlExpress icon in the Activity Bar (left side).

Next steps (optional): Generate an offline key on the Varigence website​

Once you’ve copied your Machine Code:

    • Alternatively, click the Account icon in the top-right corner of any Varigence web page.
  2. Product keys associated with your email will be displayed by license type (Subscription, Perpetual, Trial)
  3. Click the radio button next to a Product Key to select it.
  4. Paste your Machine Code into the Machine-Code field. Optionally, provide a Machine Name if desired.
  5. Click "Generate."

A window will pop up with an Offline Key linked to the Machine Code you provided.

Offline Key Generated

Copy the Machine Locked Key and paste it into BimlExpress or BimlStudio to activate the product without needing internet access.
