Acrobat thumbnails on Windows 7 32 bit not working

Hello I have a Windows 7 Pro 32 bit system which is healthy but will not display the Adobe preview thumbnail when selecting "Extra Large Icons". Now there is a lot of talk where this preview feature fails for Windows 64 bit systems so I want to stress that this is a Windows 32 bit system.
Adobe Reader DC has been uninstalled and reinstalled. Thumbnail cache cleared and so on.
I have done all the checks I think confirming that the "Always shows icon, never thumbnails" is unticked.  However the problem persists. No preview thumbnails in explorer for Adobe when selecting "Extra Large Icons".
Not sure where to look next any assistance will be great.

I have Adobe Acrobat V2015 DC on my Windows 8 machine and thumbnails show up. Make sure the side bar arrow is expanded and then click on the thumbnail icon.

No .... yes I know about that .... That is the preview window which works fine. The issue is the Thumbnail view, explorer only shows the Adobe icon rather than a miniature preview of the PDF document.

That feature has not work in any version of operating system from Vista forward in Windows Explorer. I forgot about it years ago.

This shows it clearer as to where I click
See this image - Generally the big Adobe Icons would be little previews of the PDF documents making it easy to identify which one is of interest.
JohnBusiness Consultant (Owner)Commented:
Understand. I went through all the Explorer settings. It was the least reliable feature of Windows ever, and so far as I know, it died. I would forget about it.
JohnBusiness Consultant (Owner)Commented:
For completeness, the feature worked poorly on XP, not on Vista, not on Windows 7, not on Windows 8 and not on my Windows 10 machine.
Compuit1Author Commented:
It was working earlier in the week but the system needed many Windows Updates and security patches including updating to Adobe Acrobat Reader DC. Now the feature is simply gone.
I am not keen on rolling back to restore to previous state using system restore because of the vulnerabilities the system will be exposed to.
JohnBusiness Consultant (Owner)Commented:
As I noted, the feature is horribly unreliable. I forgot about it because of that, and updates are much more important. Such is my view.

Have a look at this site, it is for 64 bit systems
It may help? They offer a patch too....

Download the fixes:

December 2014: A new, improved version is coming soon!

    With installer: (1MB)
    Without installer: (1MB)

The installer and executables are digitally signed. Thanks to GPSoftware for signing them for me.

An uninstaller is provided.

Note about jumbled-up PDF thumbnails: Some people PDF thumbnails appearing above the wrong files. As far as I can tell, it was yet another error on Adobe's part. Hopefully the latest version fixes this, although I only got one confirmation so far. Note that you will need to clear your thumbnail cache: Run Disk Cleanup from the start menu, select C:, put a tick in the Thumbnails checkbox and then click OK.

The issue I have is with Win 7  32 Bit

As I noted, the feature has be so unreliable over that past decade that I forgot about it and moved on. I do not need it. My systems are indexed and I can find files that way.
Compuit1Author Commented:
Great... Windows .... Here is a thing it works perfectly on Ubuntu's nautilus file browser! I will try the feature on a few other Windows systems to confirm.

OK I have done some testing on various systems. I uninstalled what was on them and install Adobe Reader XI.

Tested on Server 2003 -  Adobe Reader XI Operational
Tested on Windows 7 32 bit -  Adobe Reader XI Operational
Tested on Windows 7 64 bit -  Adobe Reader XI Operational

So from this I think the key is to use Adobe Reader XI - See Below:

Good for you. I do not waste my time on this stuff because vanilla Adobe on multiple systems do not work out of the box. I am happy that you got it working, but I have no need any more.
Compuit1Author Commented:
John, thanks for your input. I can confirm that Adobe Reader XI does not solve the issue for a Win 8.1 64 Bit system, however is has solved the issue on the original Win 7 Pro 32 Bit PC which had the problem after applying the Windows updates. I think the real issue in this case was Adobe Reader being upgraded to DC which cause the user to loose their PDF thumbnail preview. Reverting to XI in this case solved the issue.
You will get thumbnails automatically if you install the latest version of Acrobat or Reader.

This does not happen on my Windows 7 with Acrobat Reader DC (2015) or Windows 8 with Acrobat DV (2015) inside Windows Explorer. Thumbnails do not work on my machines in Windows Explorer.
