I had a program developed in C# VS2010 and VS2005. The program still works just fine on all Window OSs from Win 2000->XP->Windows 7. All 32 bit versions. The problem came when this program runs on 64 bit Windows7. The program fails during
the call to LoadLibrary(). Used P/Invoke method to use this function. The LoadLibrary fails with
any dll and not only the one I want. My project settings are "built on x86" and the Target Platform as "Any CPU". Infact I tried a small program(thinking that My original program is buggy), a windows forms application with two buttons.
One Button will use LoadLibrary() and one for FreeLibrary(). Same issue on 64 bit. The LoadLibrary fails with error code 193. used same P/Invoke method for making use of the native kernel32.dll in the System32 folder. Can anyone point
me if I need to do anything additonal for the program to work. I am using the C# VS2010 for development and still has to use .Net 2.0. Any suggestion is greatly appreciated.
Thanks.
Here is my code:

the call to LoadLibrary(). Used P/Invoke method to use this function. The LoadLibrary fails with
any dll and not only the one I want. My project settings are "built on x86" and the Target Platform as "Any CPU". Infact I tried a small program(thinking that My original program is buggy), a windows forms application with two buttons.
One Button will use LoadLibrary() and one for FreeLibrary(). Same issue on 64 bit. The LoadLibrary fails with error code 193. used same P/Invoke method for making use of the native kernel32.dll in the System32 folder. Can anyone point
me if I need to do anything additonal for the program to work. I am using the C# VS2010 for development and still has to use .Net 2.0. Any suggestion is greatly appreciated.
Thanks.
