I am using XP Home and am trying to use a programme which has been sent to me direct from a technical guy at Cherry to enable me to programme certain keys to carry out various functions.When I link on the attachment with the file the following Notepad message appears: FILE QUARANTINED ---------------- Microsoft Antigen for Exchange removed a file since it was found to match a filter. File name: "SetupKeyManKeyboardMouse_4006-01_EN.exe" Filter name: "FILE FILTER= FileExtension: *.exe" I think I also have to have the latest Microsoft Installer in order to use the Keyman software. Please could anyone assist me in installing the irrelevant software etc? Thanks Brian
