Scanner not compatible

Hi
I'm here again
Just this very day I've fixed this trouble, under windows 7 rtm 32 bit , by means of an 'escamotage' and now my dear and old scanjet 4400c is perfectly working!
Before of all you've todownload this driver and unzip into a folder

Then  you've to open (fromControl Panel) device manager (I've an italian OS, because I'm austro-italian  :  it's Gestione dispositivi...
You'll see a conflict or an unknown device instead of scanjet 4400c;  wel, l You have to click on update driver (aggiorna driver, in Italian) 
and look for the inf file into the folder of 'my' driver.
In the meantime it's necessary keeping the device manager under control, 'cause , at a certain point, you'll see that this driver is installed, without any yellow question mark, Well, now you've to shut off the  scanner install  windows, but , in order to do this, you 
have to  click on task manager and kill this windows, otherwise the installation goes on and your scanner will be not working!
Reboot and after  check , in device manager, if your driver is always good and with no conflict.
At this point it's necessary installing your scanner software
To do this I've used 
 the file sj659.exe from HP and , using the free software 7Zip (you'll find it online) I've unzipped this exe file into a folder.
Then I've cliccked(right)   on properties -compatibility of the executabe  and checked the box (compatibility for xp Sp3) ..and apply .
Install the soft and reboot
When windows is 'ready' You'll look for the program HP PRECISION SCAN PRO and  right click on property-compatibility , in order to check the box on compatibility for xp SP3, apply and execute.
In this way my scanner is live again:
The trick is stopping
, immediately after driver installation and install and execute in compatibility with xp sp3! 
I'hope this is working  also for you
IIf you wish, I herewith enclose also my italian documentation about this. I'd no yet  time to translate into English and German
