cannot register adme.dll

I am a user of an old app runing on Windows 2000. I tried to install this App on Vista and the app will not sucessfully work becuase it's missing adme.dll

I tried various methods to register adme.dll

I have made sure the dll exisits in system32 folder, tried to register if from command line as an admin but the dll would just not register.

I then tried profiling through dependecy walker. Below is the message it threw. Do you know it means?

LoadLibraryExW("c:\Windows\System32\adme.dll", 0x00000000, LOAD_WITH_ALTERED_SEARCH_PATH)

returned NULL. Error: The specified procedure could not be found (127).

If the DLL is not an ActiveX DLL, registering it isn't necessary.

Regarding that error? Have you tried to simply drop the DLL into your app's folder? If not, try dropping it into Vista's AppData folder? I do not know the DLL search path that Vista uses and can only guess as to why it was attempted to be loaded with a different search path.

Also, maybe, just maybe, the DLL cannot be run on Vista? Is your O/S 32bit or 64bit? Do you know if the DLL was written for Windows 3.1?

Is there a "Readme" file that came with the original software? Does the software have an associated site? If so maybe the company released a new dll that works under Vista.
