Hi everyone, I have Microsoft Office 2010 Professional Plus installed already with Outlook running and lots of e-mails which I do not want to re-install. I have tried the MTK tool but I can not activate this and getting this error, "<No installed product keys installed or possible license error>". Is there any other tool that allows me to change professional plus to volume licensing so I can activate this using MTK without re-install this? Thanks,
You can convert retail to volume but you need a complete reinstallation in order to activate with MTK. Backup all you need for Outlook before.
Thanks for the feedback again. Which part of MTL? I tried Install Keys and Check System, etc...and they all fail saying Licence Error or Porduct Key doesn't Exist....
