Hi, I just installed the about most recent version (from like two days ago) of mgnat from http://www.usafa.af.mil/dfcs/bios/mcc_html/a_sharp.html and took all the actions mentioned as being necessary in section "To use A#, you need the following" on the said website. However, I'm not able to run any of the pre-compiled exe's ... when I launch, for example, test_task.exe from the test subdirectory, I first get a message telling me the application had caused an exception that could not be handled, then I get the following debug output: >>> Microsoft (R) Common Language Runtime Test Debugger Shell Version 1.0.3705.0 Copyright (C) Microsoft Corporation 1998-2001.

Same applies to all exe's, also rapid.exe in the rapid.net folder of the rapid download package, which was pointed to on the A# website. Funnily, as soon as I compile the respective source file (most will, just a few files seem to be missing for some ...?!), I can start the exe and it runs as expected ... however, that cannot be the right way to do it for I'd have to distribute the source code of my A# applications and have users compile them like this ... I'm using Win XP Home SP 2 and I've got the .NET Runtimes installed (Versions 1.0.3705 and 1.1.4322). TIA Florian Haag
