Every time I log in, I get an error message dialog: Error starting MATLAB Connector: One or more services failed to start

I'm running Windows 10, and MATLAB R2023b, although I've seen this problem through several prior versions.

Every time I log in, a dialog box pops up with the error message:

Error starting MATLAB Connector: One or more services failed to start

I've uninstalled and reinstalled MATLAB Connector multiple times. The Connector itself seems to work when I start MATLAB, but this error message is kind of a pain. What's going wrong and how can I fix it?

Hi Garrett Mitchener,

I too have encountered this error. The error message indicates that the services is not installed properly on the compute nodes. To address this, begin by verifying whether any MATLAB services are currently active on the machine.

If you do not see any services running, run the following script located in “$MATLAB\toolbox\parallel\bin”, where “$MATLAB” is the MATLAB Parallel Server root installation folder, on the compute nodes:

mjs install 

If there are services running, run the following scripts located in “$MATLAB\toolbox\parallel\bin”, where “$MATLAB” is the MATLAB Parallel Server root installation folder:

mjs uninstall 
mjs install

Just to clarify: This problem is on a single machine, not a parallel cluster.

I've looked for the mjs script, and it doesn't seem to exist.

In C:\Program Files\MATLAB\R2023b\toolbox\parallel, there are directories gpu and web, but no bin.

Hi Garrett Mitchener

Could you share the reproduction steps and more details about the error that you encountered?

[Garrett Mitchener]

I installed MATLAB and MATLAB Connector.

I restarted the machine.

I logged in.

A few moments later, a dialog box appeared with that error message.

Hi Garrett Mitchener

Ensure that the MATLAB Connector services are set to start automatically. You can achieve that with following steps:

• Pressing Win + R to open the Run dialog.
• Typing services.msc and pressing Enter.
• In the Services window, look for any services related to MATLAB Connector.
• Right-click each service, select Properties, and set the Startup type to Automatic.

If this error still persists, than this might be best handled with MathWorks tech support. Here is the link to submit a technical support request?

I see no MATLAB related services in the Services list.
