Our client machines are running InfoPath 2003 with SP1. LiveLink needs a MIME Type for each document, and I can't find the right one for an XSN file. We have found the correct MIME type for the .xml file that uses the xsn template file, it open as 'application/ms-infopath.xml', albeit it gives us that read-only message per design. But, alas, we can not find the correct MIME type for the XSN template file, which is really the file that we want to put into the LiveLink document management system. I have tried 'application/octet-stream' to no avail. InfoPath thinks it is an xml file and barfs during the open. We can always put the XSN file into LiveLink and download it and save it, but we don't want that behavior. We want the user to be able to retrieve the file the same way they do all other files, which is to do an Open operation, not a Save operation.
