I installed VFP5.0 .ocx successfully.
I shows the installation steps below:
1. remove all VFP5.0 by VFP setup program
2. remove the leftover files by File Manager
3. re-install VFP3.0b by default setting
(after re-install VFP3.0b you will see DB4C0D00... inside registry list)
4. re-install VFP5.0 in different directory
5. OK
For anyone whom concern
Thanks for Arnon, Paul and Glenn.
