The answers to your questions:
1. Windows 7 Service Pack 1 x64 with no further Micosoft updates on Intel i7, 8 GB RAM.
2. PeWin32PRO2 Version "4.3.2.0 Jul 22 2013". We bought the licence with CD labeled "PMAC Executive Pro2 Suite V4.2.xx Release Version May 14,2014" from DT UK last year.
PeWin32Pro2 is running as administrator. We tried both compatibility mode "WinXP service Pack3" and also normal Win 7 running environement, it crashes anyway.
We are using actually the Geobrick LV IMS II, but I am sure it makes no difference since is is just a LV in a 19" Rack.
I attached a screenshot with the last error message before PeWin crashes.
With the new version of PeWin 4.4 did you update also the driver PCOMM32PRO ?
Greetings.
