HELP with Error 31037 and 336

I have problem with VB 4.0 32-bit.
Everything works fine on my computer. But on customer's computer I get error 336 (object...) or Cannot load from file error code 31037. I try OCXREG.EXE but nothing changed. I copied all OCX and DLL from my SYSTEM directory to customers comp. but error still remain. H E L P ! ! ! Received on Tue Sep 22 1998 - 00:00:00 CEST
