When starting mjs on my Windows machine I receive the following error:

wrapper | Starting the MATLAB Parallel Server service...

wrapper | The MATLAB Parallel Server service was launched, but failed to start.

When checking the mjs-service.log I see the following error:

We are currently looking into what is causing this issue. The problem appears to be with the LOGBASE and the CHECKPOINTBASE storage location.

NOTE: The log file is store in C:\Windows\Temp\mjs\Log by default in Windows.

To resolve the issue, you need to stop mjs:

mjs stop

And to start it back up with a -clean flag:

mjs start -clean

Doing this will clear out the LOGBASE and CHECKPOINTBASE storage location and default mjs to the original state. If the above does not fix the issue, you will also want to uninstall the service:

mjs uninstall

After which, you will want install it again:

mjs install

After doing so, repeat the above mjs start command and the issue should be resolved.
