.net Framework Error (HRESULT 0x8007000B)

Question

I have a C# application which was written on a 32bit windows XP machine with Visual Studio 2005. The application runs fine on Windows XP machines, however when I try to run it on a 64bit Windows 7 professional machine, I get the following dialog-box on start up:

Here is the full text from the details.

  See the end of this message for details on invoking 
just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
    <system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.

Has anyone else encountered this error and succeeded in solving it?

Solution 1

While your main app might be built for AnyCPU are you sure all the assemblies are AnyCPU? Do you have any native assemblies or assemblies that contain native code? Are they built against x86?

file:///C:/Windows/Microsoft.NET/Framework64/v2.0.50727/mscorlib.dll

This tells me that the app is running as an x64 process but it would appear that there is some assembly that isn't AnyCPU or x64 which is likely the cause of the BadImageFormatException.

One thing you can try is to run the application from a 32-bit command prompt (c:\windows\SysWow64\cmd.exe) to force it to be a 32-bit process and see if that works. If that works then there is definitely some assembly that is not AnyCPU.

Solution 2

Project Properties -> Build -> Platform target -> x86 may solve this problem.

Solution 3

One of the most common mistake is we forgot to change the test program and wrapper program to the correct platform. See the below image

(in the top bar it is showing the platform is x64 but you need to make sure if it is really exists in the 2nd image ...)

Make sure you have right configuration on the Configuration Manager...if your config do not match with the actual config of your c++ dll it will give BadImageFormatException.

I learned from the mistake after searching a lot ... and finally got this

Solution 4

In my case I had the 0x8007000B error because the app was running in 32 bit, on my 64 windows 7. I solved it by going in windows/syswov64 folder changing the MSVCR110.dll version 64 bit with the MSVCR110.dll version 32 bit.

(Just don't forget to put back the 64 dll after. Each time you need to run your 32 bit app, just move the dll 32 on it).

You could find the dll versions here (Unzip it before pasting into the syswov64 folder).

Solution 5

The fix for me was to change the Application Pool in IIS. Open the application pool properties and go to Advanced Settings... Then change "Enable 32-bit Applications" to True. The default is False for a new one. The code part was set to "Any CPU" although I have fixed issues in the past by setting the CPU to x86.
