I have developed a software application and digitally signed my installer with an Authenticode certificate obtained from Verisign (now Symantec). I signed the installer (.exe) using the signtool.exe utility that comes with Visual Studio. When I run the installer it now says my company name as the publisher instead of "unknown" which was my objective....success!I then posted the installer file on my website for distribution to my customers. The file is served by an asp:button that executes the following code when clicked:Response.ContentType = "application/octet-stream";Response.AppendHeader("Content-Disposition", "attachment; filename=CP11Full_x86.exe");Response.TransmitFile(Server.MapPath("~/Software/ContainmentPlanner/Files/CP11Full_x86.exe"));HttpContext.Current.ApplicationInstance.CompleteRequest(); When I download the installer file from my website and run it the publisher field says "unknown"!!!I then copied the file directly from my web server to my computer using an FTP client and the downloaded file HAD THE SIGNATURE (i.e. did not show publisher: unknown), so apparently the file on the web server is fine. It must be something about the process of downloading the file via the website that strips or invalidates the digital signature. I tried both Firefox and IE and got the same result.What am I doing wrong? Thanks in advance for your assistance.
