I want to remove office 2007 from my windows 7. It was running good since some days ( i lost my product box so when i update to windows 7 from vista,i kinda wanted to crack it or something like that,i edited the 'proof file' inside common files ) until today, windows auto update was on so i think it updated itself and now it doesnt work and i want to uninstalll it, but i cant, uninstall doesnt work, and i cant install it again too. I tried system back up but it also didnt help. Cant use it,cant remove it. Any help?
