Why does Styku Studio show "Invalid License" and fail to load?

If Styku Studio displays an "invalid license" error and won't load, your license key needs to be reset on Styku's end. This can happen after a software update, a Windows change, or other system-level events that disrupt license validation. You cannot fix this on your own — you will need to contact Styku support to reset the license.

What causes an "Invalid License" error?

Several common events can trigger this error:

A Styku Studio software update
A Windows update or system change
Reinstalling Windows or replacing the scanner laptop
Hardware changes that alter the computer's identity
The license becoming active on more than one machine

Important — Per Styku's Terms of Service: License keys are unique to your account and must not be shared with or disclosed to any third party. You must follow Styku's recommended download, activation, and installation procedures; failure to do so constitutes a breach of the license agreement. You may not transfer, sublicense, sell, or allow third parties to use the software or benefit from its functionality.

What to do

Confirm the error message. Open Styku Studio. If the error shown is "invalid license" or similar and the software will not proceed past that screen, this article applies to you.
Check your internet connection. Styku requires an active internet connection to validate your license. Make sure the scanner laptop is connected to the internet and try launching Studio again.
Locate your license key. Your license key is a unique combination of characters tied to your Styku account. If you need a viewing license key for an additional Windows computer, you can request one through the Styku Business Portal at styku.com/portal and Styku will generate one for you.
Contact Styku support to reset your license. Support needs to reset the license key on the account before you can reactivate. See the contact options below.

After support resets your license

Once Styku support confirms your license has been reset:

Important: Disconnect your Styku turntable and sensor from the computer before proceeding.
If you need to reinstall the software, download the latest version of Styku Studio from the Styku download link. Note that this process takes approximately 10–30 minutes on average, so plan your time accordingly.
Open Styku Studio on the scanner laptop.
When prompted to log in, use your existing Styku account email and password. Do not create a new account. If you have forgotten your password, use the Forgot Password option to reset it.
When prompted to activate, enter your license key exactly as provided and complete the activation steps.
Click Activate (or Submit) and wait for confirmation.
If activation succeeds, Studio will load normally and you can resume scanning.

Note on scan data: Updating to the latest software version will not delete your previous scans or customer profiles. Styku stores scan data both locally on your computer and on cloud servers. Previous data may be re-measured to reflect the latest measurements, but no scans or profiles will be lost.

Viewing your data on an additional computer

If you want to access client profiles on a second Windows computer (in addition to your scanning laptop), it is possible to install Styku Studio on that machine as a viewing device:

Download the latest Styku Studio software onto the additional Windows computer.
Launch the software and log in to your existing Styku account when prompted.
Input the viewing license key provided by Styku when prompted to activate the device under your account.

If you do not have a viewing license key, submit a request through the Styku Business Portal at styku.com/portal and Styku will generate one for you.

Per Styku's Terms of Service: Each additional installation requires a separately purchased license key. You may not use a single license key across multiple machines, and you must not share license keys with any third party.
