Hello, sorry for my English. My problem is this: I have an application that runs under IIS 7 before had no problem downloading the docx files, but now does not let me download. I have added the following line in servermodule OnCreate MimeTable.AddMimeType ('docx', 'word'); I tested the application in the StandAloneServer so I have no problems in downloading these files, I think the problem is the configuration of IIS but it is rare that did not happen. Someone who has had this problem? Thank You.
