If your application is a 32-bit program running on a 64-bit system, navigate to the SysWOW64 folder by typing: cd C:\Windows\SysWOW64 Use code with caution.
If you rely on older software environments that frequently require custom ActiveX or OCX components, implement these practices to avoid downtime:
(Replace with the actual OCX names included.)
It is highly recommended to download .OCX files only from the original software developer’s website or Microsoft's official support pages Security Warning: ocx newactiveexe download 2021
Many older .ocx files belong to the Visual Basic 6 runtime environment. Microsoft provides official, secure packages for these components. Visit the official Microsoft Support website.
Type the following command (replace filename.ocx with the actual name of the component if known): regsvr32 filename.ocx Use code with caution.
The "2021" in the search query is significant for two reasons: If your application is a 32-bit program running

: Ensure that the OCX file you are trying to download and use is compatible with your version of Windows and any software you plan to use it with.

On a 64-bit version of Windows, you have two regsvr32 tools: a 64-bit version in C:\Windows\System32\ and a 32-bit version in C:\Windows\SysWOW64\ . Many older, 32-bit OCX files must be registered using the 32-bit version on a 64-bit OS. You can do this by running the following from an elevated command prompt:
: Run legacy applications inside a virtualized environment (like Windows XP or Windows 7) to isolate them from modern Windows 10 or Windows 11 security policies.
: ActiveX and OCX files are a legacy technology. Microsoft has officially deprecated them and has discontinued most official support. This means security patches are no longer being developed for most of these components, leaving any system that relies on them exposed to known and exploitable vulnerabilities.
