I am using Vista Home premium 32 bit. I tried to restore, Uninstall in safe mode but still didn't work. During installation of new version, it prompted me to uninstall the older beta version. While uninstalling, the progress got struck at 94%. I left it overnight and still didn't finish.
Now I have somehow found a beta version of 2009 and installing it again. Maybe it will uninstall properly this time

. N don't worry I ll keep u all posted !

thx for your help.
