Why doesn't Styku Studio recognize my email address after a software update or logout?

After a software update or unexpected logout, Styku Studio may stop recognizing your login credentials. This is usually caused by a corrupted local configuration file that can be deleted to reset the login — your account and scan data are not affected.

Why This Happens

When Styku Studio updates or closes unexpectedly, a local authentication file called auth_v3.cfg can become corrupted. When this file is damaged, the software cannot match your email to your existing account and instead prompts you to create a new one.

How to Fix It: Delete the Auth Config File

1. Close Styku Studio completely if it is open.

2. Open File Explorer on the Styku laptop.

3. Navigate to C:\ProgramData\StykuV5.

4. Find the file named auth_v3.cfg and delete it.

5. Relaunch Styku Studio.

6. When prompted, log in with your existing Styku account email and password.

7. If asked for a license key, enter the key associated with your Styku account. If you do not have your license key, you can find it in the Styku Business Portal at https://styku.com/portal.

If the File Delete Does Not Resolve the Issue

In some cases, a new license key may be needed to reactivate the software. You can request a license key through the Styku Business Portal at https://styku.com/portal. If you cannot locate it, contact Styku Support and they can provide a replacement key and guide you through reactivation.

If this resolves your issue, no further action is needed.

If the problem persists, contact support and include: your Styku Studio version number, the exact error message shown on screen, whether the issue started after a software update or unexpected logout, and your license key if available.
