Hello,

I use

mcc -m myfile.m

in convert to make a .m file to .exe file.

In the past I used this command and it worked, but now it is no use. Command window shows me:

Error using (line 4)

Call to mcc failed with return code 1 (0x1).

Could you help me?

Could be lots of reasons. Maybe you no longer have a license for the Compiler Toolbox. Maybe there is a syntax error on that line. Attach myfile.m and I'll see if I can compile it.

Run the attached file and tell me what you see.

I have tried your solution, but does not work.

Command window sjows me:

Unable to open file "C:\Users\HP\Desktop\requiredMCRProducts.txt": Permission denied.

Error using code (line 4)

Call to mcc failed with return code 1 (0x1).

line 4 is : mcc -m width_v2

What's wrong? In the past I could create .exe files without problem..!!

If file C:\Users\HP\Desktop\requiredMCRProducts.txt exists then check what its permissions are, and ensure that your account has permission to read and write it.

If that file does not already exist, then check the permissions on C:\Users\HP\Desktop and ensure that you have permission to create new files in there.

ok, after that what should I do? If i do not have the permission? But as I mentioned above, in the past I could use the command and create the file . Now I can not!

Get the administrator to grant you access to the file or directory.

I do not have any interest in speculating on the various methods or reasons that you might have lost permission to the file or directory; just fix the permission and keep going.

Ivan, I don't think that's my program. My program, attached, does not do mcc at all. It does not do "mcc -m width_v2", and in fact line 4 is a blank line. I've attached it again. Please run it and tell us what it says.

I got this exact same error (Unable to open file "C:\Users\[]\Desktop\[]\requiredMCRProducts.txt": Permission denied.) when using a folder on my desktop. I even ran Matlab as administrator.

I moved my folder to the root of C:\, and now suddenly it works. So maybe it has something to do with permission management of the desktop on Windows.
