Mathworks Licensing Error 5005

I am using university account and it already activated licenses. However, I cannot run the script because it said "Mathworks Licensing Error 5005". I already tried reinstalling MATLAB, but this message always popped up. Please help me because it is urgent matter.

From AI:

MATLAB licensing error 5005 typically indicates a "License Checkout Failed" issue, often caused by a corrupted license file, an expired license, or failure to properly activate the software. [1, 2, 3, 4]

Here are the most effective solutions to fix this issue:

1. Reactivate MATLAB

Reactivating is the most common fix to refresh corrupted or outdated license information.

• Navigate to the bin folder within your MATLAB installation directory (e.g., C:\Program Files\MATLAB\R2023a\bin\win64).
• Right-click activate_matlab.exe and select Run as Administrator.
• Select "Activate automatically using the Internet" and follow the prompts. [1, 2, 3]

2. Delete Cached License Files [1]

If the cached license file is corrupted, MATLAB will continue to throw errors even after reactivation.

• Close MATLAB.
• Windows: Press Windows Key + R, type %APPDATA%\MathWorks\licensing\licenses, and press Enter.
• Delete the license files in this folder.
• Restart MATLAB and activate if prompted. [1, 2, 3, 4]

3. Verify License Validity (for Users/Admins) [1]

• Individual Licenses: Ensure your license has not expired via your MathWorks Account.
• Network Licenses: If you are using a shared license, the network license manager might be down or the license file on the server may need an update. Contact your license administrator. [1, 2, 3, 4, 5]

4. Reinstall MathWorks Service Host [1]

If the issue is related to the service that handles licensing, reinstalling the service host can fix it. [1]

• Follow the official guide to uninstall and reinstall the MathWorks Service Host. [1]

If these solutions do not resolve the error, it is recommended to Contact MathWorks Support for further assistance.

Thank you for your assistance. The second method works. I have another question, which is why MATLAB R2026a is slower than R2025b? I already deleted R2025b due to bug issues. When I reinstall MATLAB R2026a, I found out that it is slower to run the script? Is there any way to fasten the running process?

This question is too vague to be answered. How much slower ? What functions do you use in your script ? Try another MATLAB code and/or MATLAB Online for comparison. If you think R2026a is systematically slower on your PC than R2025b , you could contact MATLAB support.
