64-bit internet explorer! In fact your IE settings can differ between 32 and 64-bit browsers, and therefore your embedded browser can act differently than your manually launched IE (default is 32-bit). And you mentioned Java. ProE uses its own locally installed Java, not the system installed Program Files Java. There is NO Java that supports 64-bit Applets, therefore applets do not work from the embedded browser – nor from a 64-bit IE browser. Applets only work with the 32-bit browsers. Product Structure Explorer (PSE) is your best example of a Java Applet – that does not work from ProE 64-bit. He would like to know how the bet goes.
