I could not reach that if I did no read Paul's instruction: SO THANK YOU VERY MUCH PAUL I just made my 1st scan with 4500c / W7(64), in a bit different way: Do you think I am ever going to buy anything HP again? Not likely. I had issues with this when I first changed to XP but finally found a fix for that. The one thing I haven't done is put the slide scanner on during the install.

After I reboot I don't connect the scanner until the install says to. The scanner still runs with just basic windows type scanning. I deleted everything and started again - after rebooting. removed the 4500 device and reinstalled scanner device pointing to the folder with the ini file I had edited. I uninstalled the 4500 device & all software and drivers again and reinstalled. I just get HP Scanning (5590) and HP Copy (5590). I got the USB id (1305) and extracted the files, did the editing, Removed everything, I thought. Okay, I was hoping this would work for 4570c. Re-install and specify the driver in the location of your modified Hpgt5590.inf file. Go to device manager and uninstall the 4500c device. If HP Solution Center complains that it cannot find your scanner, it may be using the original 4500c/5550 driver. You will get a warning like this, go ahead and 'install the driver anyway'. In Devices and Printers select the hp scanner device and update the driver.Ĭhoose to specify driver from a specific location and browse to the extracted 5590 files you created above. If you don't know how to do this, check out this post.Ħ. To allow Windows to load our modified driver, go ahead and disable driver signature enforcement.

inf file has now been 'tampered' with, the supplied driver hash is invalid and Windows probably hasn't loaded the driver. The remaining steps deal with driver signature enforcement in Windows 8ĥ. You can Connect your 4500c scanner when prompted during the install. You might expect setup.exe to be the launcher, but it isn't. Install the software by running HPZstub.exe.

Edit Hpgt5590.inf with a text editor and replace each occurrence of '_1705' with '_1205' There should be 3.Ĥ. Extract the contents of this file using your zip application. Download the Full Feature Software and Driver package from the HP ScanJet 5590 drivers page.Ģ. In device manager uninstall the existing hp scanjet 4500 item.ġ. Uninstall any existing HP driver software for the ScanJet 4500C. Since the 5590 has a different USB product id (1705) to the ScanJet 4500C (1205), we need to alter the 5590 software package's inf file before installing.

The basic idea is to use the HP driver software for the ScanJet 5590. I've been working at getting my old HP ScanJet 4500C working with Windows 7 圆4 for a while now, and I finally cracked it! I can't believe how simple the solution turned out to be.
