Hello, first of all , i have a Toshiba Satellite A300-1NO laptop , and for the past few days i am formating my C partition, tried a lot of versions of windows 7, included the one it was in the firstplace, it's not about the windows itself i think. I used Tune hd Pro for HDD - thinking i have a bad sector, nothing . Used Repair windows - nothing Windows 7 enterprise with SP1 without that update for exploits. My issues : *Cannot install Microsoft Office 2007 or 2010 -Error : setup cannot find proplus.ww\proplusww.msi [Installed the same kit of office on another windows7 (identicaly like mine) it worked] *Cannot activate windows 7 BAD SLIC DATA After i sfc /scannow with elevated rights , it says something about corrupt files [ FRESH COPY OF WINDOWS , when it 1st boots up, did sfc /scannow and it has errors wtf ? ] Here is my CBS LOG mediafire . com /?7s8aa4de8i7udhw (no links ) I scan with antivirus software both partitions (Kaspersky & avast ) Please, i don't know what else should i do .... Bellow are some Prtscreens. Any advice would be apreciated.
