Status: Verified
SYMPTOM(s):
Error 7203 when running .NET Open Client on 64-bit environment
Could not connect to the AppServer: <message text>. (7203)
Exception:SessionPool : NoAvailableSessions[Could not connect to the AppServer: General Error: is not a valid Win32 application. (Exception from HRESULT: 0x800700C1). (7203) ]
Trace:Progress.Open4GL.DynamicAPI.SessionPool+NoAvailableSessionsException: SessionPool : NoAvailableSessions[Could not connect to the AppServer: General Error: is not a valid Win32 application
FACT(s) (Environment):
Calling the .NET proxy from a .NET application
Using .NET 2.0 Framework
OpenEdge 10.1x
Windows 64-bit
CAUSE:
The .NET application has been compiled with the 'Any CPU' Compiler option. It needs to be compiled with the 32-bit compiler option.
FIX:
For ASP.NET 2.0, run as a 32-bit application instead of 64-bit.
For further information about how to switch to 32-bit version of ASP.NET, check http://support.microsoft.com/kb/894435
For a Windows Forms .NET application, set the /platform:x86 option for the compiler in the .NET project instead of 'Any CPU'.
For further information about how to set this compiler option in the Visual Studio environment, check the following MSDN article:
