OS : Microsoft Windows XP with Media Center Edition Problem : When I click Start/Programs/Microsoft Excel, the Excel Logo just binlks one on the screen and disappears. Excel does not start. No Excel File opens from Windows Explorer. When I try Safe mode, Installer windows pops up with message "Please wait while Windows configures MS Off XP with Frontpage andthen Excel 2002 Opens in Safe Mode. I have tried all the steps mentioned in MS Site (xlb rename method/pip rename method/ Registry Keys alterations etc as suggested). I have also run /Unregserver/Regserver method. No method ahs been successful. Re-installing twice has not helped. Stopping Speech Recognition has aslo not helped. I have made a step by step check of all setting in Xl* filetypes in Explorer / Folder options. Disabling Kaspersky Antivirus Internet Secutiry 7 has also not helped. Request help from anyone on this. Thanks in advance.
