How to Register OCX Files in Windows

1. Locate the file 'regsvr32.exe.' This is often found in C:\WINDOWS\SYSTEM32, but it may be elsewhere. If you can't find it in that folder, click 'Start,' then 'Find,' and run a search for it on the drive on which Windows is installed.
2. Right-click on the OCX file you want to register and select 'Open With.' When the application list appears, click 'Other.'
3. Navigate to and select 'regsvr32.exe' and click 'OK.' Opening the OCX file with this program will register it.
