Office 2007 file association

Hi everyone,

we are trying to thinapp Office 2007 and deploy this on Clients which have Office 2003 installed.

The file associations for Office documents should always point to Office 2003 applications.

This works if none of the Office 2007 applications is startet, but when Word 2007 for example is executed and the focus lies on it, every Word document ist opened in Word 2007.

We don't want the system to react this way. Has anybody an idea how we can solve this problem?

Thanks
