Under normal circumates the dll is loaded from System32 folder unless it is present in the same folder as exe. Since i do not know if this dll is managed or unmanaged or COM dll. You can attempt to register dll. http://social.msdn.microsoft.com/Forums/en-AU/netfx64bit/thread/813f13ec-0180-496a-8af0-b57dfd4e4de4[^] If it is managed dll, maybe you can consider putting it as GAC (Global Assembly Cache) Edit: If you have 64bit os, for 32 bit process put in SysWOW64, for 64 bit process put in system32

I don't know the entire answer, however this much I can tell you: 1. wmp.dll contains native code, hence it can't go into the GAC. Either it holds COM components (which I don't know much about), or it requires P/Invoke to call individual functions (which I have descibed to some length here[^]). And I do expect it to be COM. 2. If you use P/Invoke (which also means you don't "Add Reference"), the DLL is located in the good old way, in the exe's folder first, then through the system environment variable "PATH", which typically contains
C:\Windows\system32\and many others. The app will start even when the DLL isn't present, however every reference to it will obviously fail during app execution. 3. OTOH, if you have a hard reference to a DLL (as with "Add Reference"), then the DLL file (and its dependencies) must be present for the app to load successfully. 4. I'm pretty sure there are several CP articles that refer to wmp.dll, so you could go and have a look how they handle things. :)Luc Pattyn [My Articles] Nil Volentibus Arduum
