Information about the installation of the VTF plug-in for MS PowerPoint and MS Internet Explorer:
This page uses an active-X plug-in for the visualization of VTF files in the Internet Explorer. If this plug-in is not yet installed on your computer or is available in an older version you are asked if you want to install it. After your confirmation the installation operation will be started automatically. If there were no request and the object is not displayed the security settings of your Internet Explorer are too strict.
If you use another browser, the plug-in is not available.
