We had thought of that, but it doesn't hurt to double check...
The SPSS directory and both of the executables I'm concerned with are
marked to allow "read" and "read & execute" for the "Users" group. When
I look up the "Users" group on the machine I've been using for testing,
I find it has a member called "condor-reuse-vm1". That account is
marked "disabled", but I assume that doesn't matter since it can
successfully run other jobs (like the diagnostic batch file I used to
query the environment for comparison, and the "spssprod" executable
which does run successfully, but can't spawn its child, or whatever the
Windows parlance is).
