winopen error when trying to open a directory

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 :)

The error message sounds, like you try to open a file but do not associated it with a program. Please post the failing command and not only the working code.

The failing code, for example, is winopen(pwd)

An what is the answer of "pwd"? Perhaps you've defined this accidently as a variable before?

[Yuval Weissler]

No, it's legit. Also, like I've said, it's an example. No directory opens, and code that once worked and hasn't changed, now stopped working.

My guess is that the problem is outside Matlab, but I don'n know what.
