Oh, yes....I didn't use a snapshot at home because I didn't have to
deal with the issue of creating, or writing to, network files.

As it turns out, I was able to access Matlab at work today (that's
where I really need the app).  Your solution is great for future
reference, since I won't always have access to the floating license.
