Ruby.exe: Permission denied


I’m trying to run some rspec test driving a web browser with selenium.

The problem is I get this error:
c:/Programs/ruby/bin/ruby.exe: Permission denied

Nevertheless, I do have the permissions
-rwxr-xr-x 1 IVPazmin Administ 70737 Oct 21 2012 ruby.exe

I’m trying to run the command through a rake task.
Also, I’m trying to run from a git bash on a windows machine.

What permissions may I be missing to grant?

Thanks in advance
