Hi,
I believe the issue is related to the license type. When I use a license server, MATLAB R2024a works without any problem.
However, when I switch to an online (SSO) license, the application gets stuck on the white startup screen and never shows the authentication window.
I have already disabled the Windows firewall to rule out local network issues, but the behavior remains the same.
This suggests that the issue may be linked to the SSO authentication process rather than the installation itself :(

Contact Mathworks at <Product Support Page>. They support install/startup issues.

Independe on whether you plan on contacting MathWorks Support or get help here, a bit structure is always helpful. Release information is included here, but what about the operating system?
Can you have a look whether this article helps?

I do not understand what bit structures have to do with the question ???

I agree my wording was confusing. What I meant to say is "providing structured information is important for asking good questions". And in this case the OS information is missing.

Hello
if you can give me the FAQ number could be easier to find the "solution"

It's FAQ question number 16.3. The link sends you right there, at least it should.
This is what it says:
"The causes for crashes are many and complex, and complicated to figure out, especially if you don't have access to the source code. This is why it's best for The Mathworks to work on your crash issue. Asking other users in the Answers forum may provide an answer but the chances are slim. Your best bet is to call The Mathworks at (508)647-7000 and explain to them the circumstances for your crash. The Mathworks gives free support for all installation problems, even by telephone and even for Student, Home, or Trial versions. Note, this is just if MATLAB itself crashes, not if it's your m-file throwing an error (red text in the command window) or a DLL or mex file causing the crash. "
If you can't call the main US number, go to the contact us page and call the distributor in your local region. See the bottom of this page: https://www.mathworks.com/support/contact_us.html?s_tid=hp_ff_s_support
and enter your country.

Hello,
I ve the same problem.
I’m experiencing a blocking issue with MATLAB R2025a and R2025b.
Despite several complete installations and uninstallations, the software still won’t launch properly.
Observed behavior:
  • When I start MATLAB, the interface opens to a white screen showing only the MATLAB logo in the center;
  • The application remains frozen indefinitely;
  • No SSO (Single Sign-On) login prompt ever appears;
  • No error message is displayed.
Please note that MATLAB R2023b works perfectly on the same machine using my perpetual license.
Could you please advise on how to resolve this issue or provide the diagnostic steps (e.g., activation logs, clean uninstall procedure, etc.)?
Thank you in advance for your help.
Best regards,

Answer from AI:
A white screen with only the MATLAB logo can be caused by a graphics or licensing issue. To fix this, try updating graphics drivers, forcing a different graphics renderer with the -softwareopengl flag, or running the MATLAB activation application to complete the licensing process. If the problem persists, try resetting MATLAB's preferences or performing a clean reinstallation.
Potential solutions
  • Update graphics drivers: Outdated or incompatible drivers can cause display problems. Visit your graphics card manufacturer's website to download and install the latest drivers.
  • Force software rendering: Open your terminal or command prompt and start MATLAB using the matlab -softwareopengl command. This forces MATLAB to use software rendering instead of hardware acceleration, which can resolve some display issues.
  • Run the activation tool: Start the "Activate MATLAB R2025" application or MathWorksProductAuthorizer.exe to ensure MATLAB is properly licensed. After a successful activation, try launching MATLAB normally.
  • Reset preferences:
  • Close MATLAB.
  • Press Windows Key + R to open the Run dialog.
  • Type %appdata% and press Enter to open the Roaming folder.
  • Navigate to MathWorks\MATLAB.
  • Rename the release folder (e.g., R2025a to R2025a_old).
  • Create an empty folder with the original name (e.g., R2025a). This will force MATLAB to generate new preferences.
  • Check for system compatibility: Ensure that your operating system and hardware meet the minimum requirements for MATLAB R2025.
  • Perform a clean reinstallation: If the issue continues, uninstall MATLAB, delete any remaining folders, and reinstall the program, making sure the installation completes successfully without errors.
