I've been trying to run a c file in matlab with mex function. I have been getting this same error that's below. I cannot edit the names of the directory files because I do not have admin access. Everything was created automatically. I downloaded VS2010e as the compiler.

Also, do you have write permissions to your directory? Try running the mex command after starting MATLAB "as administrator".

Hi,
seems like you are trying to compile the example file in the directory where it comes with MATLAB. Under Windows 7 or Vista the UAC blocks write access to the C:\Program Files\... folders, which results in such an error. Try to copy that file to a folder where you have write access and compile it in there.

In addition, I am also uncomfortable with the use of the name "mexcallmatlab" - I would recommend using a different name because this clashes with the name of the MEX-API function mexCallMATLAB.

Hi, I am using Visual Studio with matlab and I get the same error as your when I try to compile something with the mex command:
Please how did you solve it??

Most likely a bittedness missmatch. Make sure you configured the project to be a 64bit project. Otherwise the 32bit compiler tries to open the 64bit kernel32.lib which results in the error you get.

I had similar problem. I was running MATLAB 2019a under windows 10.
To solve the problem, please try to run with Windows 7 compatible mode, and admin.
See attached picture. Good luck!
