The default output is tuple or tuple, not 2D numpy ndarray.

When this happened at TSRI, it turns out that a newer version of comtypes was installed, not 0.6.2 in files of this site.

During debugging, we found that the replacement safearray.py found in pyscope that gives ndarray output can not be used to replace the 1.1 version one. This needs to be updated. In the mean time, the workaround is to use the 0.6.2 version. See Installing_comtypes

Use workaround in the mean time.
