Z-Suite older than 1.4.0 won't run

I'm having issues with surface finish on the bottoms and tops of parts with Z-Suite 1.4.1 and wanted to try older versions to see if they worked any better.  When I try to run any version of Z-Suite older than 1.4.0 the program fails to load and I get the error message in the screen grab below.  Has anybody else seen this problem?  Is there a solution?

I've filed a Bug Tracker report.
