wrong file association after dual installation Office 2007/2010 RRS feed

  • Frage

  • Both office versions work well but hitting in file explorer at a document file XLSX and PPTX it will start version Excel or Powerpoint 2007, at DOCX it will start Word 2010. If I try to change the file association nothing happens. Also there are no versions listet. Windows XP (!) tells me that the file is associated with (f. e.) "Microsoft Office Excel". I did not find the point to tell the system that this should be the executable from Office14 folder.

    Has somebody an idea which registry entry I must change for this?

  • hy detlef,

    i think the following key could it be:


    maybe my file association could help. it opens Excel 2010



    Windows Registry Editor Version 5.00

    "Content Type"="application/vnd.openxmlformats-officedocument.spreadsheetml.sheet"










    before you do this, please export your old key from your registry. than you wont have trouble to restore


    best regards

  • Hi George,

    thanks for your help. This did not help. Before I posted here I screwed in the registry a lot. But sorry I don't remember if it were exact the keys you wrote. But after changing 10 keys or so without success I gave up. Then by this forum I got remembered for the Repair Installation, it was right.
