I tend to use the winopen function alot, to open files with their default program, or directories locations with windows explorer.
I've recently replaced my PC with a laptop (both were 64bit), and all of the sudden, winopen stopped working when trying to open a directory. The following exception is thrown: The file name association is incomplete or invalid (from win_open_mex).
It's important to emphasize that my code hasn't changed, and it's worked before. Also, when trying a Matlab example: winopen(which('meshgrid')), the function works.
Please help :)
