Getting an error each time opening a MFile for editing?

Hi,

I have this machine with MATLAB R2015b on it? it seems it has some problem, running MATLAB. Any time I try to open a M-File it generates the following error:

Can't reload 'C:\Program Files\MATLAB\R2015b\bin\win64\mm_rmidd_mi.dll'

Error in rmidata.RmiData

Error in rmiml.RmiMlData

Error in rmiml.RmiMlData.getInstance

Error in rmiml.getAll

It doesn't matter whether I click on the file to be opened in the editor or I used the editor command. Both give me the same results.

The editor do seem to open properly though.

The same error appears when I close the editor.

And before you ask: Yes, I checked and that file is present in that location and I do have read/write permission to it.

Any help is highly appreciated.

My problem (on R2018a) was due to a shadowed pathdef.m

>> which -all pathdef.m

What fixed things for me was removing the duplicate, and then issuing 'restoredefaultpath'
