I have an installer which detects the installed version of Microsoft Office by looking at the registry entry HKEY_CLASSES_ROOT\Word.Application\CurVer.
It works well for Office 2000, XP, 2003 and 2007, and it works well even on Office 2010 over Windows Vista/7. But after installing Office 2010 Home and Small Business (the free trial version) over Windows XP SP3, this registry entry doesn't exists.
So my question is: How can I detect if Office 2010 (any version of it) is installed ?
Thank you in advance.
