We have some users that are not getting a Ole Preview window for Reader 9.3.3 in our application. AcroRd32.exe seems to start fine by itself and can display the document. But now the preview is no longer running. It seems like this is caused by a security policy, as not all users were initially effected. But now more are and we need to know what specifically is effecting it to have IT unblock it. Our application uses Windows standard methods and other Ole types like Excel or Word documents display fine. Only PDF's are no longer able to be displayed.
