.m files are not opening in editor

Dear MATLAB users, I've just installed matlab 2018a. whenever I doubleclick on a .m file Matlab starts instead of opening the desired file in a new tab in the editor eventhough Matlab is already running. Thanks in advance

I did. I reset matlab as a default program to open the *.m files but it didn’t help.

Just to be clear, every time you open an m file directly from a folder, a new version of matlab boots and opens, correct? Is it the same 2018a version of matlab each time?

Exactly. Thx for the link. The problem looks similar. I’ll try it

[Samhar Saleh]

As I have just said, a new instance of MATLAB is launched when i double click a *.m file. but the file itself is not opening in the new instance just its path. I tried to uninstall the 18a and install 17b but the problem remains unsolved. I am not runnig MATLAB as an adminstrator as mentioned in the link above and no other version was installed before 18a.

Hello,

I had the same problem in r2018a. You should download the file on below link, run the code inside on it.

Then, run the composed .reg file. Now, You can reopen the MATLAB. The problem should be solved.

Dear Jan,

I am sorry to inform that you have just leave the link. You didn't explain step by step.
