First, make sure you have the latest from the HP website and if those don't work, try compatibility mode. There's a tutorial link in my signature (I didn't write it, Ian did.). Hope this helps!
You could try downloading a tool like WinRar (www.rarlabs.com) and then see if it lets you extract the main driver exe file to it's constituent parts. The drivers for your printer will no doubt be bundled somewhere within these files and you can install it manually, instead of using the HP software wizard.
I've tried everything in this post and I'm still unable to install the HP 5440. Is there a generic printer driver I can use? I don't need the full functionality of the printer.
