I am running Windows XP Professional SP3 and I have just installed the .NET Framework 3.5 and the Mendix Business Modeler version 2.5-beta (build 25). When starting the new Modeler for the first time, I get the error printed below. After clicking 'Close', nothing happens and the splash screen just sits there. I have to end the Modeler.exe process to get it to close. What to do? Kind regards, Jonathan van Alteren An unknown error has occurred during the execution of the modeler. It is advised to save your changes and restart the modeler. Please file a bug report containing the details of this error.

Please check your regional settings at "Control Panel > Regional and Language Options" or "Configuratiescherm > Landinstellingen".
Do you use English (US/UK)? Click 'Customize' / 'Aanpassen' and make sure that the point is used as decimal separator instead of the comma.
Hopefully this fixes the problem. And we will work on a real solution for 2.5.0, of course.

Have you installed .NET 3.5 SP1? It can be downloaded from here.
Also, did you copy the entire details message? (You can use the handy new "Copy details" button for this!) Having the entire details message will help us solve the problem much quicker.

No, I didn't install SP1 for the .NET Framework 3.5. I followed the instructions on the 'Moving from 2.4 to 2.5' page, which does not mention Service Pack 1. But yes, I did copy all the details (see the stack trace above).

Hmm.. as it seems, I did install .NET Framework 3.5 SP1 after all. So unfortunately, SP1 doesn't resolve the problem.
