2019b installation problem

I'm using 2019a Matlab version and have just tried installing 2019b together with the toolboxes. I see the following set of errors on the Matlab screen, when I try to launch it. The screenshot is attached.

Looks like something has gone wrong with your installation. Please contact MathWorks support to resolve this.

Answer 1

[ALEXEY BARAN]

The solution was to delete the Matlab shortcut and launch Matlab.exe

Answer 2

[CAM]

I had this same problem with 2018b and now again with 2019b. Last year, Matlab Support solved it with the following solution:

=============================

Thank you for contacting MathWorks Support. The error you are receiving is usually caused by MATLAB having a pathing error. To resolve this error, please run the following commands in MATLAB in order:

restoredefaultpath

savepath

Once done, restart MATLAB and see if the error persists, if it does, please let me know so I can provide further troubleshooting.

=============================

Hope it works for you.

[ALEXEY BARAN]

It doesn't help: the error persists.

[Pablo Trucco Pignata]

It worked perfectly for me. Thanks.

[Andreu Guasch Casadevall]

Had the same problem this morning with 2019b. The proposed solution worked for me. Thanks!

I had the same problem with 2019b on linux. It solved the problem thanks!

[Neil Thompson]

Thank you, that worked.

[Stefan Grandl]

Yes, that helped! Thanks! In addition to ALEXEY BARAN's solution above - both did it for me.

[Milton]

I had the same problem after upgrading from 2019a to 2019b and also with the 2020a prerelease.

This fixed it. Thanks!
