multilanguage support cannot open file error on word viewer

Question

i have a multilanguage supported sharepoint 2010 site and in it there is a document library.(english default,turkish installed later) when i click a word document on library if my language selection is english it gives Cannot open file "_layouts/WordViewer.aspx?id=/DokumanMerkezi/file.docx". error and the url on ie adds download.aspx?SourceUrl=http://portakal/_layouts/WordViewer.aspx?id=....&DefaultItemOpen=1&DefaultItemOpen=1

(... etc : my file path)

if i click to open word file when my language for the site is in Turkish it gives no error and open files in word app viewer. here is the link in Turkish http://portakal/_layouts/WordViewer.aspx?id=file... etc

the difference is as you see in english it tries to redirect to download.aspx?Source.. in turkish it directly opens with wordviewer.aspx.. what may be needed to solve this,thanks

Answer 1

This sounds a lot like a bug in Office Web Apps.

When Office Web Apps is installed, it overrides the file links in sharepoint. It looks like there is some language selection related error in the functionality that does the overriding. Could you try enabling / disabling the "Always open in client application" site collection feature?
