Windows allows you to manually register an OCX or DLL file using a program called Regsvr32.exe that comes with the operating system. In a 64-bit version of Windows, both a 32-bit and 64-bit version of Regsvr32.exe are included with the system. To register a 64-bit OCX file, you will need to use the 64-bit version located in the "System32" folder, not the 32-bit version located in the "SysWoW64" folder.
Press the Windows orb to open the "Start" menu. Click "All Programs" and then click "Accessories." Right-click on the "Command Prompt" icon and choose to "Run as Administrator."
Type the command "Regsvr32
Wait for a confirmation that the OCX was registered if you didn't choose to run Regsvr32 in silent mode. Restart the system once the process is complete.
