Here’s a fix for Adobe's PDF preview handler on 64-bit versions of Windows. Preview handlers’re lightweight components which let you view various file types within programs like Windows Explorer in Windows Vista and Windows 7, Outlook 2007 and Directory Opus via bundled plugin. Adobe Reader comes with Adobe's PDF preview handler but the installer has a mistake which means the preview handler does not work on 64-bit systems. People’ve been complaining about this for over two years with no official response as of September 2009. It turns out the problem can be fixed via a simple registry change. Here’s a manual fix: 1. Open RegEdit and go to: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Classes\CLSID\{DC6EFB56-9CFA-464D-8880-44885D7DC193} – there should be an existing AppID value, incorrectly set to {6d2b5079-2f0b-48dd-ab7f-97cec514d30b} – change the AppID value to {534A1E02-D58F-44f0-B58B-36CBED287C7C}
