.PDF icon corrupted on Windows 7

Question

If I double click on the .PDF, files I can open them with Foxit PDF reader, but the icon is wrong (I have the icon of the unknown files). How I can fix this problem?

Answer 1

Try rebuilding the Windows 7 icon cache.

• Open up a Command Prompt (Start -> cmd)

• Run:

  del /ah "C:\users\YOUR_USERNAME_HERE\appdata\local\iconcache.db"
  

• Reboot

Answer 2

I found the solution to this problem. I am running Windows 7 64-bit and using the 32-bit Foxit Phantom software.

When the program is installed, the default registry entry for the program icon in:

HKEY_CLASSES_ROOT\FoxitPhantom.Document\DefaultIcon

is:

"C:\Program Files (x86)\foxit software\foxit phantom\Foxit Phantom.exe"

Apparently Windows 7 64-bit needs the additional icon reference number if an icon is stored in an .exe (as in this case) or other icon containing files. The correct value for the registry key to correctly display Foxit Icons is:

"C:\Program Files (x86)\foxit software\foxit phantom\Foxit Phantom.exe,-128".

After saving and rebooting, the correct icon should be displayed.

Answer 3

I had the same problem, however it turned out the icons weren't actually the icons of unknown files but miniatures of the first pages of the (pdf and other) documents.

To make it show normal icons: Go to the C drive, Settings, Advanced settings and check for 'always show icons, never miniatures' (translated from Danish so I hope it makes sense).
