I recently did a wipe of my machine and reinstalled Vista Ultimate SP1 (32 bit). Previously with Vista I had thumbnail preview of Acrobat PDF icons. However, after doing the new install of Vista and then installing Acrobat 9 Professional (Entire CS4 suite actually), I just have this odd looking icon for all my PDFs (I say odd, because it doesn't really look like an Acrobat icon without the thumbnail preview normally does).
I have uninstalled and reinstalled Acrobat 9 Professional, and I have also installed Acrobat Reader 9 and set that to be the default PDF viewer. I have also gone to advanced system settings and made sure performance was set to "Adjust to best appearance."
Despite all of these things, they're still not showing up properly. Not a huge deal, except that I work with PDFs extensively, and it's really annoying! Other icons, for graphics for example, do show up with the proper thumbnail icon.
Any help would be appreciated.
