Hi Crtystal,
There is a problem with the Word 2007 Chinese Translation group showing up in the Review tab of the Ribbon. If you open Excel 2007
do you have the Chinese Translation group showing there?
If you have a CD/DVD retail version of Office 2007 then uninstalling the trial version, restarting the PC then installing the retail
version is generally considered to be a better practice.
If you had a prior version of Office on the computer then the prior version add-in could be causing the error message you're seeing,
or the Asian language support files for Windows through 'Regional settings' in the control panel might not be installed.
What Add-ins are listed in Word 2007 (and Excel 2007) under
Office Button=>Options=>Add-ins
in each app.
==================
Hi Bob
the online Translation tools works.
i install my office 2007 over a trial version (without uninstall the trial
version). so will this be the reason? >>
