"License Mismatch Detected" Error When Activating Tunneller License

This guide will help you resolve a common issue that may occur when attempting to license Tunneller. The problem arises when the system displays a **"License Mismatch"** message, indicating a discrepancy with the registered license. Follow the detailed steps below to resolve this issue quickly and effectively.

To resolve the "License Mismatch Detected" error when attempting to activate the license for Tunneller, follow these detailed steps:

Step 1: Close the License Wizard

Before making any changes, ensure the License Wizard is completely closed. This is crucial to avoid conflicts while modifying system files.

Step 2: Access the License Directory

1. Open File Explorer on your computer.

2. Navigate to the following path:

C:\ProgramData\Matrikon\Licenses

3. If you cannot find the ProgramData folder, it may be hidden. To reveal hidden folders:

- Go to the top bar in File Explorer and select View.

- Check the box labeled Hidden items to display hidden files and folders.

Once you have access to the directory, proceed to the next step.

Step 3: Rename the "tunneller" Folder

1. Inside the Licenses folder, locate the subfolder named "tunneller."
2. Rename this folder so that it starts with an uppercase letter, changing it to "Tunneller."

This change is important because some system processes distinguish between uppercase and lowercase letters, and this discrepancy can cause issues when activating the license.

Step 4: Restart the License Wizard

1. Open the License Wizard.
2. Follow the usual license activation procedure, entering the Activation Key and other provided details.

After making this adjustment, the license activation should complete without errors.
