Where can I find 3DxOffice?

[3Dconnexion]

You can find deprecated plug-ins under Download Drivers --> Choose Device --> Archives on the 3Dconnexion web site. While 3Dconnexion continues to make these plug-ins available, they are no longer officially supported or maintained. They can be used as is.

If you update your 3Dconnexion software (3DxSoftware), you may need to reinstall some of these plug-ins again.
