Installing .OCX files is a relatively simple process. On a 64-bit Windows system, you can use both 32-bit and 64-bit OCX files. Place 32-bit OCXs in the '/Windows/SysWOW64' directory and 64-bit OCXs in the '/Windows/System32' directory.
Installing .ocx files directly into the software application folder where the corresponding .exe file is located offers several advantages and is generally a safer approach than immediately placing them in the Windows system folders.
Some OCXs need to be "registered" with the operating system to function correctly. This involves adding details about the OCX to the system registry.
