One Identity Reports

I'm deploying a Report built with the Report Editor to a customer running 8.1.2.  The report uses conditional formatting and expressions to compose text.  The customer has two environments.  On the one environment, I can enter expressions using the syntax in the Stimulsoft documentation... which looks like C++ or C#.  On the other environment, I get syntax errors on all expressions.  There it seems to want VB syntax.  What can be causing this?  I don't see any setting in the Report Editor related to expression syntax.
