After installing Acrobat from CS5.5 on windows 7 x64 generating pdf thumbnails in windows explorer got broken, here's how i fixed that.
1. open reader x preferences (crtl + k), go to "General" tab, click "Select Default PDF handler" button and choose Reader
2. if thumbnails got fixed after that - great!
3. if not or even got worse (for me Reader assigned wrong program to handle PDF files) go to Control Panel in windows, click "Default Programs" or something like that (i can't tell how exactly it is in english because i use polish version of windows)
4. in window that opens click this
5. browse for .pdf and click "Change Program"
6. in window that opens select Adobe Reader, click OK, close control panel window
7. now open Adobe Reader from start menu/shortcut, press crtl+O (open file) and navigate to any folder containing PDF files
8. you should see windows generating thumbnails in the "Open File" dialog
9. it's (hopefully - at least for me it worked fine) fixed
hope this helps
Absolutely fabulous!! This worked like a dream!! I only had to do the first part of what you explained & VOILA, I had thumbnails back!!
THANK YOU, THANK YOU, THANK YOU!!!!! This had been driving me NUTS & I had searched all over the internet & nothing worked.
I am SOOOO glad I found your post!!!
This symptom occur because a 64-bit process that runs on a computer that is running an x64-based version of Windows cannot load the 32-bit .dll files that are required by some program features.
You may try the following work around:
You must use the 32-bit version of Windows Explorer. The 32-bit version of Windows Explorer is located in the %windir%\Syswow64 folder on the computer that is running an x64-based version of Windows.
To use the 32-bit version of Windows Explorer, follow these steps:
Click Start, click Run, type the following in the Open box, and then click OK:
Note The placeholder Drive_Letter represents the drive where the x64-based version of Windows is installed.
For more information:
Some Windows Explorer extensions and some Control Panel items are not displayed on computers that are running an x64-based version of Windows
Now check if the issue is resolved.
You may want to try the following steps:
PDF thumbnail view via the Acrobat reader:
1. Run Acrobat Reader. In Reader, click File > Open and navigate to the folder(s) containing your PDF file(s). If necessary, move the slider to show all your PDF files.
2. Cancel out of Open and exit Reader.
3. Open Windows Explorer and navigate to the folders(s) containing your PDF file(s).
4. Click Views and move the slider until you see PDF thumbnails.

I've got the following issue with my Adobe Reader X, under Windows 7 x86: after having cleaned my PC with "Disk Cleanup" option, I can no longer see my .pdf thumbanils (books covers) for my .pdf docs. I have tried the view option, I have tried reinstalling Adobe X, but the problem persists. I think, the disk cleanup might have deleted some registry entries. It is interesting that under my wife's account, one can see these .pdf thumbnails (book covers). please find attached a screen capture that helps you make an idea of how worse it is. Once again - I'm running Windows 7 x86 and not x64.
Thank you in advance for your support
Well if nothing works you can try this:
Open Adobe Reader X
Click on File and Open.
It will bring the Open dialouge Box.
Browse to the location wehere you want to show PDF in thumbnail view (Let's say Desktop)
In open dialouge box Change the view to Thumbnail.
Need not to Even open any file.
Close the Open Dialouge Box and Close Reader X.
Go to Desktop you'll find all PDF in Thumbnail.
Hope it Will Work, Good Luck

For those with this thumbnail problem that are running Windows 7 in 64bit format this is the fix to solve the problem. I will be sorting out my PC when I get home.
Thanks for all the other suggestions on how to fix the thumbnail problem. Unforunately, none of them worked for me on my laptop except for Bad213Boy's solution. It's really sad to find so much joy in watching your pdf's change to thumbnails as you look through the files in Explorer.
I would recommend Adobe makes a significant donation to Bad213Boy for all the effort that he has put in to solve a problem with their software!
Thank you for the link to the fix that really works
On a PC without admin rights, doing Reader > File > Open on your folder(s) seems about all that works.
Sadly these thumbnails expire quickly with normal use, as if to taunt your lowly non-admin status.
