We were able to render the new office file types by explicitly putting the filename when loading the file, it seems our S3 url generator is appending some post-fixes in the URL passed to the web viewer.
Our problem now is that we're unable to view the old office files (doc, ppt, xls) and some files that is required by our client (msg, eps) i tried converting the files to PDF before rendering it but the converter always fails for those file types, I can convert image types (jpg, png, gif, bmp) just fine, except for those types mentioned above.
Any idea what I can do?
