Missing OCX files for Windows XP, Windows Vista and Windows 7

When trying to run UT 3xx Windows instrument interface on Windows Vista, Windows 7 or some Windows XP installations, you may receive an error stating that either (or all) mscomm32.ocx, gage32.ocx or threed32.ocx files are missing. The Interface does not run. These ocx files are no longer distributed with Windows and must be installed separately. Please follow the download and installation instructions below to install and register the missing OCX files. Please note that after installing the above ocx files on the latest versions of Windows, the instrument interface will work properly however there may be some cosmetic UI issues.
