My OS is Windows 7 and when trying to reload printer software (D110 series ptr.), I get a message that hp zidr12.dll is missing from my system32 folder. Also, the HP Solutions Center doesn't get loaded. I've tried several different fixes and reloads, but nothing helps so far. I'm tempted to go find that file on the internet and paste it in my system32 folder, but not sure that will repair my proble.
Apparently the HP support & download sites don't have that file and it doesn't show up on their searches.
