I am trying to install MATLAB on a Windows computer, but the installer will not run.  How do I resolve the issue and launch the MathWorks Installer?

There are a few reasons the MathWorks installer might fail to run on Windows without displaying an error message or creating a crash logs:
  • System Requirements
  • Security Software
  • Administrative Permissions
  • Corrupt Installer
  • Path Contains Non-ASCII or Accented Characters
  • Located on a Network Drive

System Requirements

Your computer may not meet the system requirements for the release of MATLAB or other MathWorks product you are attempting to install. See the system requirements page for more information:

Security Software

Some security software will interpret the MathWorks installer as a false positive, and prevent the installer from running. To resolve this issue, add the MathWorks installer to your program whitelist, or temporarily disable your security software.
You may need to contact your system administrator to modify your security software settings. If you are unable to change your security settings then you can boot your computer into Safe Mode with networking which will suppress your security software as long as the computer is in Safe Mode.
Note: Before booting in Safe Mode, verify that BitLocker is not enabled on the machine. BitLocker will prevent startup in Safe Mode.

Administrative Permissions

You must be a local administrator to install MATLAB. If you are not a local administrator, contact your system administrator for assistance.

Corrupt Installer

If the installer fails to launch and provides no error message, the installer may be damaged or corrupt. This may happen because network security software modified the file in transit: however it could just be random corruption.
If you suspect the installer is damaged or corrupt, redownload the installer from the MathWorks website.

Path Contains Non-ASCII or Accented Characters

If your MathWorks Installer is located on a path that contains non-ASCII or accented characters, the MathWorks Installer may not launch.  This will most likely be the case if your username has a non-ASCII or accented character and the MathWorks Installer is located in the user's Downloads folder.
To launch the installer, move the Installation files to the root of your C drive.

Located on a Network Drive

This issue could be caused if you are running the MathWorks installer from a Network Drive due to lack of permissions. To resolve, download the installer on a local drive and run it from that location.

Yes, this is totally feeble. What idiot programmed this installer? Super fragile.

For me, the installer was on a local drive but I fixed the problem by moving it to the system drive

I had the same problem and this C++ thing wouldn't work for me. Then I found out that the issue was me using MSI Afterburner with Riva Tuner Statistics Server! Just shutting down both of these programs and the Matlab installer worked just fine. If anyone else has this issue, make sure you don't have these two troublemakers running.

I had the same problem, and none of the above worked. In my case, I had Matlab2018 and wanted to update to 2020b. I asked the Mathwork support, and they suggested to go to the extracted folder (_temp_matlab_r2020b), navigate to bin/win64 and run setup_legacy.exe. That solved the problem.

Moving the setup folder to the system drive is the only solution that works for me. (for ver. 2020b on Win10 PC)
Thanks goes to Emile Bourban.

I tried the solutions above, but nothing works for me. When I launch the setup file, nothing happens.

Check this page
Or install the previous version, R2021a.
