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 'Administration' or one of its dependencies. An attempt was made to load a program with an incorrect format.

Source Error:
An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.

Assembly Load Trace: The following information can be helpful to determine why the assembly 'Administration' 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\Micorsoft\FusionEnableLog].

Version Information: Microsoft .NET Framework Version2.0.50727.4927; ASP.NET Version:2.0.50727.4927

Causes and Fixes

If you are running IIS 7 with a 64 bit operating system, follow these steps to resolve the problem:
1) Go to Control Panel > Administrative Tools > Internet Information Services (IIS)
2) Expand down to the Application Pools in the tree.
3) Right click on the application pool that is being used and select Advanced Settings
-------------------------------------------
NOTE: The application that is being used by ION Enterprise web applications is usually one or both of the following:
Classic .NET AppPool
DefaultAppPool
If you do the recommended settings changes for these application pools, that should be sufficient. It may be useful to note that it is possible to check exactly which application pool is being used by doing the following:
(a) Start > Run > "inetmgr"
(b) In "Internet Information Services (IIS) Manager, expand the tree in the left hand pane to MACHINENAME\username \ Sites \ "Default Web Site" and click on "Default Web Site" to highlight it.
(c) In the right-hand pane, click on "View Applications".
(d) Check the "Application Pool" that is referred to under the column of the same name.
-------------------------------------------
4) Change the Enable 32-bit Applications to True
5) Set Identity to network service.
6) Click Ok.
7) Still in the IIS Manager, in the left pane, Select Default Website > In the Middle pan, double click the Handler Mapping".
8) In the Right Pane, click Edit Feature Permissions" and configure the permissions for read, script and execute.

    • It is ALSO advised that you remove Enhanced Internet Explorer Security. You can perform this by navigating back to the Server Manager, and Selecting Configure IE ESC. Once the configuration window appears, disable the enhanced security for all users.


If you are running a version of IIS before 7 with a 64 bit operating system follow these steps to resolve the issue:
1) Click Start, click Run, type cmd in the Open box, and then click OK.
2) Change to the following directory: \\%homedrive%:\Inetpub\Adminscripts
3) In the Adminscripts folder, type the following command, and then press ENTER: adsutil.vbs set w3svc/AppPools/Enable32bitAppOnWin64 1
4) Type iisreset, and then press ENTER.
5) Navigate to the correct 32bit framework directory (C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727 for v2 on x64) and run 'aspnet_regiis.exe -i'.
6) go into IIS -> Web Service Extensions and "Allow" 'ASP.NET v2.0.50727 (32-bit)'
