Error 53

I have written a program in VB 5 that utilises my company's API.
I have created an install routine using the VB Application Setup Wizard. I have installed this program on 95, NT Workstation 4, and NT Server 4 with No Problems.
On our customer site, we get an error when we run the program on their NT Server 4 box.

Error 53 Could not find llkernel.dll


llkernell.dll is my company's DLL which is in the c:\winnt\system32

The thing is the file is in place, and c:\winnt\system32 is on the path.
The DLL has been registered.

Any ideas? Is there known bugs with the Setup Wizard on VB5?

Cheers
Mike

could it be that your llkernel.dll references other components or DLLs that are not installed by the setup program?
