SharePoint: Excel – Open in Client Application

Bei Meldungen wie “Sorry, but to open this workbook, your computer must be running a supported version of Microsoft Excel and a browser that supports opening files directly from Office Web Apps.”

gibt es verschiedene Ursachen:

  • DLL nicht registriert
  • zu viele DLLs registriert (versch. Office Versionen)

Zuerst Prüfen ob folgendes AddOn im IE vorhanden und enabled:

2014-09-10 13_28_59

Wenn nicht, die Datei “Owssupp.dll” registrieren.

z.B. mit FixIt:


  • Go to Control Panel, Programs, Uninstall a Program.
  • For each Office program that is not an Office 2010 program, select the item and click Change, Choose Add or Remove Features, Click Continue.
  • In Installation Options, expand Office Tools, Click Windows SharePoint Service Support OR Microsoft SharePoint Foundation Support, Choose Not Available, Click Continue. You must do this for all Office family programs that are not Office 2010 including earlier versions of Office Project or Visio.
  • Once configuration is complete, in Programs, click Office 2010, click Change, Choose Repair, Click Continue. (Note: A reboot will be required after the Repair completes)
