Error registering DLL

[ByzantianX]

I have a problem that I can't register a Delphi dll with regsvr32. I always kept getting message: LoadLibrary ("nameofDelphiDLL&quotfailed. GetLastError returns 0x00000485.
I've checked dll within other Delphi applications and it works perfectly.I need a dll that could work in different environments, not only in Delphi, so, that's why I need to be able to register that dll with regsvr32. Could anyone help me with some idea what might be wrong, please?

Do I have to declare function DllRegisterServer or something?

Now, I used a simple sample dll from Object Pascal for Delphi book and regsvr32 didn't register it, again, with the message:"D:\minmax.dll was loaded but the DLLRegisterServer entry point wasn't found. DLLRegisterServer may not be exported or a corrupt version of dll is in memory..."
Also, when I tried to use procedure RegisterComServer, I kept getting messages that procedure couldn't be found. I really don't know what might be wrong, Delphi Help does not offer any details and I can't find any solution in literature I have (Marco Cantu's Delphi, for example). Please, help!
