I cannot install Office Professional Plus 2013 on Win 7 64-Bit. Neither x86 nor x64 Office 2013 can be installed sucessfully.
I've tried to uninstall the previous versions of Office 2007, via using the Microsoft Fixit tool
http://support.microsoft.com/kb/971179, but after that, it still failed to install Office 2013.
I've tried to remove all traces of the new Office installed on the system via
O15CTRRemove inhttp://support.microsoft.com/kb/2739501, but this fix cannot work with error code
