Summary: Get used to seeing that message if you waste your money on this scanner. Just ended an hour long phone call with HP customer support trying to install the software on windows XP. They know about the problem. The installation package includes the "Access Denied Utility" which was ineffective on my system. They are researching the problem and promise to call call later.
contrary to 'jim's' statement - Vista drivers have ALWAYS' been available.

Summary: this scanner isn't that fast, and is 'top' heavy w/ software, but you want high resolution; and customizable output possibilities, this isn't a bad choice. As to the mis-informed fellow 'Jim' - who states there are no Vista drivers, please find them here: web-link not allowed - Google hp and select 'drivers & downloads' then search for g4010 - you'll be able to select from various OS...
Summary: This is the second G4010 I purchased. Like everything else it has its good points and its bad points. The slide adapter is a little cumbersome to use, the user interface could use some work, especially the preview screen when you're doing slides. But, its scans are pretty darn good!
Summary: Great scanner. It's quick, easy to use and scans photos, magazine articles, etc. flawlessly! I am using it to scan old family photos as well as magazine recipes that I want to save and the quality of the scans is fabulous!
Warning: The paper handler shown does not come with this item.

Summary: When I bought this scanner the picture showed a paper handler on top of the scanner. I purchased this item based upon the associated photo that shows a paper handler on top of the HP4010. This photo does not represent the item you will be purchasing from them. You will only get the flatbed scanner as the words say. Amazon.com is notorious about their poor descriptions of products, but this is the worst I've seen in the 5 years I've been a Prime customer.
Summary: As with all HP products this one does not let you down. I have the HP 8500A Officejet Pro which also has a scanner; however, it does not have the slide/negative scanning capabilities that I need. Great product, excellent price.
