Just curious if this is where it writes the information? Or if you're into reg editing this will add Trillian or whatever up there, SO modify to what you want. Installit = path to the Trillian EXE file: with a backslash \ and whatever follows I believe this comes from Kellys site HKEY_LOCAL_MACHINE, "SOFTWARE\Microsoft\Internet Explorer\Extensions\{2ef50289-0ea7-482e-a30b-4947a81e44cf}", "ButtonText", "Trillian", REG_SZ HKEY_LOCAL_MACHINE, "SOFTWARE\Microsoft\Internet Explorer\Extensions\{2ef50289-0ea7-482e-a30b-4947a81e44cf}", "clsid", "{1FBA04EE-3024-11d2-8F1F-0000F87ABD16}", REG_SZ HKEY_LOCAL_MACHINE, "SOFTWARE\Microsoft\Internet Explorer\Extensions\{2ef50289-0ea7-482e-a30b-4947a81e44cf}", "Default Visible", "YES", REG_SZ HKEY_LOCAL_MACHINE, "SOFTWARE\Microsoft\Internet Explorer\Extensions\{2ef50289-0ea7-482e-a30b-4947a81e44cf}", "Exec", Installit & "Trillian", REG_SZ HKEY_LOCAL_MACHINE, "SOFTWARE\Microsoft\Internet Explorer\Extensions\{2ef50289-0ea7-482e-a30b-4947a81e44cf}", "HotIcon", Installit & "Trillian.exe,117", REG_SZ HKEY_LOCAL_MACHINE, "SOFTWARE\Microsoft\Internet Explorer\Extensions\{2ef50289-0ea7-482e-a30b-4947a81e44cf}", "Icon", Installit & "Trillian.exe,191", REG_SZ HKEY_LOCAL_MACHINE, "SOFTWARE\Microsoft\Internet Explorer\Extensions\{2ef50289-0ea7-482e-a30b-4947a81e44cf}", "MenuText", "Trillian", REG_SZ sorry but thats from my VB app but it contains what you need. For those reg minded let me know if what keys it writes as I'd rather do it that way since I have HOME and thus not gpedit.msc
