WIN7 X64 PDF缩略图 补丁软件 修复PDF BUG

WIN7 X64 PDF缩略图 补丁软件 Introduction: This page contains simple fixes for Adobe's PDF preview handler and thumbnails on 64-bit versions of Windows. Before I looked into this, people had been complaining about it for over two years with no official response. Only the thumbnails fix is still needed, except if you upgraded from Vista to Windows 7, where both fixes may still be needed. Half a year after I published the information, Adobe finally incorporated the preview handler fix (but no thumbnails fix, and they leave the preview handler broken if you upgraded from Vista to Windows 7) into the installer for Adobe Reader 9.3.2 (April 2010). Maybe in 2011 Adobe will manage to fix the thumbnails as well; until then you can get my fix for them below. :-) Preview Handler Preview handlers are lightweight components which let you view various file types within programs like Windows Explorer (in Windows Vista and Windows 7), Outlook 2007/2010 and Directory Opus (via my bundled plugin). Adobe Reader comes with Adobe's PDF preview handler but the installer had a mistake which meant the preview handler did not work on 64-bit systems. It turned out the problem could be fixed via a simple registry change. The change is described below and a small program which performs the fix is also provided for your convenience. Unlike the thumbnail fix, described below, the preview handler fix should no longer be needed by most people, since Adobe have finally fixed their installer, but it's still provided in case it helps repair things. If you had Adobe Reader installed under Vista and later upgraded to Windows 7 then you will probably still need to run the preview handler fix once to clean up a registry value which Adobe set inconsistently between the two OS versions. If in doubt, run the fix and it will tell you if anything needs to be done. If everything is good already then the preview handler fix won't change anything.
