I created very simple Context Menu using Shell Extension in C#. It works fine under Windows XP 32 bit but under Windows 7 64 bits menu items not appearing.
I tried to build Setup output to x64 but no effect.
Simple Source contains ContextMenu and Setup project is under http://bit.ly/9nGd41
Looks like Wow6432 should be handled by Setup project, same for registration and adding to Global Assembly Cache
I would be appreciate for help / suggestions with this issue.
Check the DLL's platform in Visual Studio and make sure it's 64-bit. 64-bit processes can't load 32-bit DLLs into their process space (and vice versa, naturally).
To build a 64-bit version of your DLL, use Visual Studio's Configuration Manager to create a new solution platform. Select X64 (instead of X86 or any platform), and rebuild the project. There are also command-line switches for C# compiler, if you are using scripted builds.
I have to strongly recommend you stay away from any code written by Esposito. As usual, his P/Invoke declarations in the ShellExt folder are completely wrong, they cannot work in 64-bit code. Publishing this code was very irresponsible in the first place, shell extensions should never use a .NET CLR version before 4.0. Visit pinvoke.net if you want to rescue it.
Hi, I'd the same problem. You need to change InstallUtil.dll in your setup file. I wrote a article in my blog about it. http://artyomgrigor.wordpress.com/2010/10/06/register-shell-extension-context-menu-also-on-windows-x64-part-2/
