License Management Guide

How to Reactivate Your Lemon Squeezy License

Complete step-by-step instructions for reactivating your MLabs Revit plugin license when moving to a new computer or after reinstalling your operating system.

Important: For Lemon Squeezy Licenses Only

This guide is specifically intended for customers who activate their MLabs plugins using a Lemon Squeezy license key.

Reactivating a license is commonly required when you:

  • Switch or upgrade your computer: Moving your daily Revit workflow to a new workstation or laptop.
  • Reinstall your operating system: Formatting your drive, resetting Windows, or performing a clean system reinstallation.
  • Upgrade core computer hardware: Hardware modifications that generate a new machine signature.

Because single-user licenses are limited to a set number of active devices (typically 1 seat), Lemon Squeezy requires you to deactivate the previous machine instance before your key can be reactivated on the new machine.

Frequently Asked Questions & Troubleshooting

Why do I see the error “License key has reached its activation limit”?

This message indicates that your license is still registered to your old computer or prior Windows installation. Follow Step 1 and Step 2 above to deactivate the old instance in Lemon Squeezy. Once the seat is released, try activating again in Revit.

Can I deactivate my license if my old computer crashed or is no longer accessible?

Yes! Because Lemon Squeezy manages licenses in the cloud, you do not need physical access to your previous machine. You can visit https://app.lemonsqueezy.com/my-orders from any computer, phone, or browser to deactivate the old instance.

What should I do if I changed my email address or cannot access my orders?

If you no longer have access to the email address used during purchase, please contact us through our License Support Page. Provide your order number, invoice details, or purchase receipt so our team can help update your account.
