Do you happen to share network drive with a Mac, or did you happen to copy your files over from a Mac?

I didn't understand your question ?

XCode is a compiler for MacOS. If you run Windows 10, this message should not appear. As Walter asked already: Did you copy files in the prefdir folder from a MacOS installation? But even then modern Matlab version look for a file like "mex_C_win64.xml" and a collision with another preferences file is unlikely.

You can try to re-create the preferences files. Rename (not delete) the preferences folder and try, if the automatic re-creation and a new mex -setup solves the problem. Then you can copy the newly created compiler setup file to the original folder and restore the former preferences folder.

If this does not help, try:

mex -v -setup

and post the results here.

I am experiencing a similar problem when trying to run the mex setup. This is the result from the mex -v -setup

>> mex -v -setup -c

In MATLAB, command

!osascript -e 'do shell script "xcode-select -switch /Applications/Xcode.app" with administrator privileges'

Also, make sure that you start up XCode once, as it is necessary to agree to the XCode license before you can use XCode from MATLAB.
