I assume this is COM dll
Try opening .vbp file in notepad and see where it is going to.Sometimes it has wrong references.

nope it is not a COM dll, it is a standard dll, i reference it using.
Public Declare Function HookKeyboard Lib "KTKbdHk.dll" (ByVal hWnd As Long, ByVal MsgID As Long) As Long
Public Declare Function UnhookKeyboard Lib "KTKbdHk.dll" () As Long
Public Declare Function Hooked Lib "KTKbdHk.dll" () As Long

The KTKbdHK dll works well in 95/98 but can cause serious problems in ME, 2000, and XP if not careful.  There is an update available for xp etc. but then it doesn't run in 98.  
I used it for awhile but had to include both versions and use OS checking to determine one to use.
