I have an application that uses the webBrowser control provided by Microsoft to display a PDF file for the user. It was found that when the application runs under x64, the program loads and opens in Adobe Reader and does not appear in the user control. (Link: http://social.msdn.microsoft.com/Forums/en-US/winforms/thread/06ad960b-7c5e-459c-9261-ca9d0e4ac88f/ ) Has anyone found a workaround for this problem other than compiling the application in x86?
What to expect; A 32-bit PDF Reader Document is downloaded only by a 32-bit browser. When this does not happen, you go to the normal file download file directory.
