PDF thumbnails not showing up in folders

I just loaded Vista Ultimate 64-bit. Folders only show thumbnails for JPGs and not PDFs. In past, when I had 32-bit Vista, the thumbnails showed up for PDFs. All view settings are correct. Hidden files, file extensions boxes, etc. Box to always show thumbnails and not icons.
I have disabled user accounts and all security, but, all I get for PDFs is the icon for Adobe Reader 9.2. It won't show a thumbnail. In same folder, all JPGs show up. I really miss this feature which worked in XP and Vista 32-bit. What is going on??

Hi Ben9000,

Welcome to Microsoft answers!

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:

Drive_Letter:\windows\syswow64\explorer.exe /separate

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.
