In case anyone is interested, this explains why the Access Denied errors occurred, and why switching to bash solved the problem:

Another solution to the Access Denied problem is to put the following line in init.el:

(setq org-babel-C-compiler "gcc-4")

Then you can keep using the Window shell instead of bash. However, this still only solves part of the problem. The output is still blank.
