I have a Photosmart C5280 All-in-One Printer, which seems to be printing okay, but when I tried to install the software, it said it wasn't compatible. What do I need to change? I went into the setup folder and started to change everything in there to Vista SP2 compatibility, but there is so many exe files in there! I would like to be able to use the software, because I need to know my ink levels, etc.
