My PB2017 application (Build 1681) crashes in production with the same dlls and exe as in the development on Microsoft Server 2012 R2 Standard. The only difference is the PB2017 is installed on the development server which is a partition of the prod one so it should not be a problem.  I have 12.1 running on it with no problem.

see below.
