Windows 7: Explorer Preview Pane

16 Jun 2012   #1

Windows 8.1.1 Pro 64-bit
Explorer Preview Pane

I can't get .pdf's to show in the preview pane in explorer. I can see .doc, .txt, .jpg, .xls,.htm and .html. Any help will be appreciated. I have Win 7 64-bit and Adobe Light 9 reader.

I found this on line, but It didn't work. The pic didn't paste.

There’s a new 64-bit operating system, Windows 7, and a new version of Acrobat Reader (9.1). And the bug is still there. Here’s what you see if you try to preview a PDF file in Windows Explorer under Windows 7 x64: The problem is caused because Adobe registers the wrong preview handler, even though Microsoft explicitly documents the correct settings, The fix involves replacing the incorrect registry value with the proper one.

The preview handler fix tool:
  • Tells you if anything needs fixing and offers to fix things if so.
  • Understands differences between XP, Vista, Windows 7 and upgrade installs.
  • Requests elevation via UAC.
  • Checks that you're using 64-bit Windows.
  • Checks that Adobe Reader is installed.
  • Checks that Adobe Reader's preview handler is associated with PDF files. (If not you'll be asked if you want to associate it. This does not affect what happens when you double-click PDF files; use the Open-With menu for that.)
  • Checks that Adobe Reader's preview handler is registered under both the 32-bit and 64-bit registry (the latter is required for it to work under 64-bit Office 2010 beta but not the retail version of Office 2010).
  • Allows you to undo the fix. (Only the fix itself. If you changed the association and want to go back then you'll usually have to reinstall or repair-install your alternative viewer.)
  • Does not need to be installed or uninstalled and, other than the fix itself, leaves nothing behind.
  • Is digitally signed so you can detect if it has been tampered with.
If you want to apply the preview handler registry fix by hand, or are just curious about the detail:
  • First, read all of the section above about the tool. Most of the information also applies to doing the fix by hand.
  • Open RegEdit and go to:
    If it doesn't exist then you may not have Adobe Reader installed in the first place. Or Adobe may have changed the way they install it. Or you may be on 32-bit Windows. Or you may be on 64-bit Windows but have run the 32-bit version of RegEdit.exe by mistake.
  • 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}

Now see if the same registry path exists but without the Wow6432Node part. If it does exist, make the same change as before. If it doesn't exist then that's fine and you can skip this part.
