MailEnable webmail error

[Vinoth]

Hello,

I got following error after upgrading the plesk


Server Error in '/MEWebMail' Application.
Could not load file or assembly 'MEWebmail' or one of its dependencies. The module was expected to contain an assembly manifest.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.BadImageFormatException: Could not load file or assembly 'MEWebmail' or one of its dependencies. The module was expected to contain an assembly manifest.

Source Error:

The source code that generated this unhandled exception can only be shown when compiled in debug mode. To enable this, please follow one of the below steps, then request the URL:

1. Add a "Debug=true" directive at the top of the file that generated the error. Example:

<%@ Page Language="C#" Debug="true" %>

or:

2) Add the following section to the configuration file of your application:

<configuration>
<system.web>
<compilation debug="true"/>
</system.web>
</configuration>

Note that this second technique will cause all files within a given application to be compiled in debug mode. The first technique will cause only that particular file to be compiled in debug mode.

Important: Running applications in debug mode does incur a memory/performance overhead. You should make sure that an application has debugging disabled before deploying into production scenario.

Assembly Load Trace: The following information can be helpful to determine why the assembly 'MEWebmail' could not be loaded.


WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure logging.
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

Something wrong with ASP.NET 2.0
If it is Win2008r2 check that you have enabled .NET Framework 3.5.1 and role service ASP.NET for IIS.
Also I suggest you contact Support Team. They will check and fix this issue directly on your server.

BadImageFormatException: Could not load file or assembly

The exception that is thrown when the file image of a dynamic link library (DLL) or an executable program is invalid. If you get a BadImageFormatException when interfacing with a native DLL, it almost always means that you are trying to interface with a 32-bit DLL while running in the 64-bit CLR, or vice versa. In most cases you might be facing the problem with your website after deploying on server.

Make sure that you are not having 32-bit / 64-bit conflict. So, you need to adjust your application pool to Enable 32-Bit or 64-Bit accordingly. Set the Target platform setting on your c# EXE project, not your class library project. Alternatively, you can ship both 32-bit and 64-bit DLLs with different file names, define separate P/Invoke stubs for each version, and decide which one to call at runtime. The easiest way to do this would probably be to wrap your native calls in an interface (e.g., INativeMethods) and choose which implementation to instantiate at runtime based on IntPtr.Size. With this method, you could still target AnyCPU.
