I have a Windows 7 (Home Premium Edition) laptop which came with pre-installed Office 2007 Trial version. In order to install Office 2007 full version, I have already uninstalled the trial version using the steps provided in Microsoft support site (http://support.microsoft.com/kb/971179). Now when I tried to run setup.exe to install Office 2007, I am getting the error message "The language of the installation package is not supported by your system". I am not sure why this error pops out... could anyone please help me to fix this? Thanks.
