PowerShell script for Windows (Provisioning new VM): vnc+offline+license+file+exclusive

1. Visit the Vendor’s License Portal (e.g., RealVNC Customer Portal).
2. Select "Offline License Generation".
3. Paste the Fingerprint.
4. Check the box: "Bind license exclusively to this hardware (No floating)".
5. Select your tier (e.g., 5 concurrent viewers, 1 server).

1) Obtain vendor license requirements

• Find the vendor’s offline activation documentation or contact support. You need to know:
  • Action: Run a weekly inventory script that collects vnclicense -list into a local SQLite database. Prove to the auditor that every exclusive file matches the server hostname.

  Step 2: The Sneakernet Aris copied those hardware IDs onto his USB stick (the classic "sneakernet" approach).

  Error C: "License file exclusive limit reached"

  Cause: You tried to copy the .key file to a second machine. Exclusive files have a 1:1 ratio. Solution: You must purchase a separate exclusive file for each seat. There are no floating offline licenses. Your servers cannot legally touch the public internet

  • Run vendor-provided utility to produce a Host ID or fingerprint.
  • Use listed system identifiers if instructed (MAC address, OS UUID, machine serial).
