Welcome to the LicensesVault support hub. Below you will find answers to frequently asked questions regarding order fulfillment and key validity, alongside step-by-step activation instructions for major software platforms.

Part 1: Frequently Asked Questions (FAQ)

1. How and when will I receive my license key?

License keys are delivered instantly and automatically upon successful payment completion. You will receive:

  • An official email containing your unique product key code and download links.
  • Immediate access inside your LicensesVault Account under My Account > Licenses.

Note: If you do not see your email within 5 minutes, please check your Spam/Junk folder.

2. Are your software keys genuine and permanent?

Yes. All keys sold on LicensesVault are 100% genuine retail or OEM licenses sourced through legitimate software distribution channels. Once activated, perpetual licenses (such as Windows 11 or Office 2021) remain active permanently on your machine unless specified as a subscription product (like Microsoft 365).

3. What should I do if my key displays an error during activation?

  1. Ensure you have installed the exact edition matching your purchase (e.g., Windows 11 Pro key will not activate Windows 11 Home).
  2. Verify there are no typos or unwanted spaces when pasting the key.
  3. Check our Common Error Troubleshooting section below.
  4. If the error persists, take a full-screen screenshot of the error message and send it to [[email protected]] for a prompt replacement.

4. Can I transfer my license to a new computer?

  • Retail Licenses: Yes. You can deactivate the license on your old computer and reactivate it on your new PC.
  • OEM Licenses: No. OEM keys bind directly to the motherboard of the first computer they are activated on and cannot be transferred to a completely different PC.
