If you are getting errors when reinstalling the product, proceed as follows
You extract the Windows installer file PowerPointAddInSetup.msi from the Speech-Over exe file (it is really a zip file) with WinZip and put it in a folder say C:\SpeechOver\PowerPointAddInSetup.msi
Now do a forced re-installation by command line,
To enter the command ine first do Start/Run/Cmd and then enter:
msiexec /fa "C:\SpeechOver\PowerPointAddInSetup.msi"
where C:\SpeechOver is the folder where you extracted the installer zip to, and contains the installer file PowerPointAddInSetup.msi.
