Hi, I have encountered similar problem. In case of opening the .xls (MS Excel) or .ppt (MS PowerPoint) files which are served from BlobStore in Google Doc Viewer, Google Doc Viewer can not display them. Error message from Google Doc Viewer is "Sorry, we are unable to generate a view of the document at this time.".
However, .doc (MS Word) and .pdf (PDF) files are worked fine. In addition, .xls and .ppt files are displayed fine when they are served as static files (not from BlobStore) like image or CSS files. The application set "application/vnd.ms-powerpoint" for Content-Type of PPT file. ------- Http Header information for PPT file ---------------- < HTTP/1.1 200 OK < accept-ranges: bytes < Content-Type: application/vnd.ms-powerpoint < Content-Disposition: attachment; filename="abc.ppt" < Date: Mon, 12 Sep 2011 18:13:58 GMT < Server: Google Frontend < Content-Length: 102912 ---------------------------------------------------------------------------- Are there anything I can try? Any information is appreciated. Thanks, Hideki On Sep 9, 1:05 pm, Joshua Smith <[email protected]> wrote: > I've never heard anything more on this.
