I have an Intel Celeron 466 Computer with Windows 98 SE, 128 MB RAM, Diamond Viper V770 Display, Creative DVD5241E Drive, and Rockwell HCF 56K Data Fax RTAD PCI Modem. Norton Windoctor regularly displays the error message “The Active X/COM section of your Windows Registry contains one or more invalid entries”. The details are: “Missing or Invalid Key: “AtWorkRenderingshellPrintTocommand” refers to an invalid command entry “C:Program FilesWindows UpdateRTF ”” and “Missing or Invalid Key: “CLSID {65006770 - D9CF - 11CF - A036 - 00001B4EAD07}InprocServer32”. The Key “CLSID...” refers to missing file AMFILTER.DLL”. Windoctor fixes the above but not permanently. I sometimes notice that when I start up the computer the words "Aborting installation" appear. Apart from the very occasional crash on startup, the computer starts without any problem and the CD ROM drive works fine. Can you explain the above and offer a possible suggestion?
