After updating from Adobe Reader 6 to version 9.1 my associated icon on several machines has now turned to a blank icon.
If I click the .pdf file it opens fine in version 9.1 - after reinstalling version 9.1 it still hasnt fixed the problem.
I've looked in the registry and the the defaulticon entries under the HKEY_CLASSES_ROOT under the acrobat key appear to be correct and pointing to the correct file location for the AcroRd32.exe
I know this issue has been raised before in these forums and am just wondering if anyone had managed to resolve it.
Depending on your Windows version, use the TweakUI powertoy and run 'Repair Icons'.
Good idea didnt think of that.
I was going to use the sysinternals (now part of microsoft) registry monitor tool to try and find out which registry entries it was attempting to use to display the icons when i opened up an explorer window with some .pdf files in them.
Tried TweakUI didnt make any difference am afraid.
