Compile error (461): Member or data member not found.

Hello,
I tried that but no benefit. It shows a Compile error (461): Member or data member not found. So, the form holding the OCX will not open. No, I think the code is in line.
There must be unusual running interference. But I am not able to figure out this. (In which case it is probably something obvious but my old eyes are just not seeing it).
I've tested the registry and the whole thing seems to be correctly registered and in sequence. The .dll file, MDIVWCTL.DLL is in the right directory etc. But there must be another program that is stopping the ActiveX control, miDocVew from starting.
I appreciate your attention. Please help me to solve this. Thanks in advance.
