If you absolutely positively must edit a file that is stored in one of the MATLAB installation directories, then you need to use Run As Administrator for your MATLAB session.

However, what you should be doing instead is storing the files somewhere that is not under a MATLAB installation directory. Your entire Real experiments directory should probably not be stored under the MATLAB installation directory.

R2018b is not supported on Windows 7 or earlier. If you are using Windows 8 or later then the operating system itself prevents you from storing files inside C:\Program Files

I am using windows 10

[Walter Roberson]

Windows 10 is designed to prevent you from writing into C:\Program Files .

At this point, the question is no longer why it does not work now (it is Windows 10 security and always has been for Windows 10); the remaining question is why it ever worked at all. There is a Windows Registry entry that can be used to turn off the protection of C:\Program Files and it is possible that had been set, disabling important system security.

You should give up on hoping to be able to write into C:\Program Files and move the files to a different directory.
