I got to install the client application in the 9x client PC. During the installation, there is an error occurred that "RCAPIOCX.OCX" failed to register. I tried to uninstall the client application and delete the RCAPIOCX.OCX from the window/system directory. When I re-install again, the error of failure to register is always appeared. I used run command "regsvr32 /u RCAPIOCX.OCX" to unregister, but the return value is error. How can I unregister the OCX? Any thing that I can proceed. Please advice. Thank you.

The main reason you would get the unregister error is if you uninstalled the program and tried to unregister the .ocx that wasn't registered to begin with, here comes the error. Of course, if the .ocx didn't register to begin with, you don't have tounregister it or even try to do so.

One good way to unregister the .ocx is to try RegCleaner. That one will let you remove any entries from the registry that were left behind by uninstalled programs. Also, it shows the entries for programs that are still installed. Be warned, you better know exactly what you have on that computer and exactly what you want to remove or here comes LOTS more errors. Fortunately, it has a backup of removed entries available to be replaced if something does go wrong. It's available from www.nonags.com in the Power Tools section. Another good way to unregister something is to search for it and delete any matches that you find. Run regedit from the "Start/Run". Do a search for RCAIOCX.OCX. if you find anything, delete it. Naturally, BEFORE you do this, make a backup of the registry.

Have Fun!!
