Error Message - File is Not Writable (Simulink 2019a)

When saving a Simulink file (slx or mdl) a message appears "The file "C:\pathname\filename.slx" you are trying to save is not writable. Simulink can attempt to make it writable." After selecting option "Make Writable and Save" an error message appears: "The file C:\pathname\filename.slx" you are trying to save is not writable." The file was originally created in release 2018a and did not have this issue when saving. Similar messages occur when attempting to export back to release 2018a. How can a file be made writable?

Hello Mathworks - any update here?
I'm seeing the same exact problem running Matlab/Simulink 2019a on a PC and accessing/storing models on a linux file server. The permissions on the linux file server are wide open - RWX allowed for all - and still the "file is not writable" error occurs when I try to save.
I will try moving my repository to the same PC where the Matlab license is installed ... removing the linux file server & samba from the equation. However my confidence of success is not high based on Roy's earlier post.

I have the same problem. I cannot save any simulink file. Once I am trying to save my file, I get the message "the file ... you are trying to save is not writable." After any modification I need to save the file with a new name. Please advise me on this matter.

Try to uninstall MatLab and reinstall it directly onto your main hardrive (for me it was C:).
Fixt the problem for me.
Hope this helps...
