Fix for Adobe PDF preview handler bug in 64-bit Windows

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}

WOW - finally someone made it easy to fix this stupid problem. I had this problem on VISTA as well as WINDOWS 7. It amazes me that Adobe dont bother to make this an update. Why does it have to rely on people who have nothing to gain to find how to fix these annoying issues.

Well done!
