On Win7 x64, if it matters. I installed Office 2003, then, some time later, Office 2007. Unfortunately, the installation left the association of .doc files set to Word 2003. I have tried using "Open with..." to reassociate the file, then browsing to C:\Program Files (x86)\Microsoft Office\Office12\WINWORD.EXE (which, when double-clicked, opens Word 2007) and selecting it, then clicking OK, which results in Word 2003 opening the file!

Since "Microsoft Office Word" is set as the default opening application when the "Open with" dialog opens, and Word 2003 is also "winword.exe," the incredibly simple-minded dialog refuses to change the location of the executable, and leaves the 2003 version as the default. Right-clicking the "Microsoft Office Word" up in the "Recommended Programs" list to try to access its properties and change the location does nothing.



Am I going to have to uninstall Office 2003, or is there another way to overcome this OS imbecility? Thanks.
