First off I tried the great VueScan software from Hamrick which worked wonders when upgrading customers to Windows 7 in the past. However, that software didn't work with the Kodak scanner and so was no good.
Then I came across this tutorial: http://www.pcpro.co.uk/blogs/2012/08/06/getting-older-drivers-to-work-in-windows-8/
This isn't really for the faint-hearted, which is why I attempted it!
I found the relevant INF file at C:\Program Files (x86)\Kodak\AiO\Scanner2
Named: EKAiO2Wia.inf
It is advisable to copy the file before working on it.
Upon opening the file I found that it is a "long" file with lots of sections and lots of file references. I tried copying certain lines but I couldn't get it to install. Then I thought, the only thing Windows knows to identify the driver is the Device-ID, so why don't I just change the ID of one of the other devices.
So that's what I did, I changed one character and then the install worked according to the PC-Pro blog.
A snippet of the inf file is included below - this is the relevant 64-bit section of the file.
I looked at the device ID of the Kodak esp 9250 - to find this run devmgmt.msc, select the scanner, then properties and details and finally "Hardware Ids"
This image isn't for the actual Kodak 9250, which has id: VID_040A&PID_4065, this is just shown as an example.
On the far right of the INF file you can see &pid_4066, this is the value I changed because I figured being only 1 number different it would be the closest match.

Once you've done this you need to remove the driver signature which is at the top of the file, I've done it by simply inserting a semi-colon before the CatalogFile statement:
[Version]
Signature="$CHICAGO$"
Class=Image
ClassGUID={6bdd1fc6-810f-11d0-bec7-08002be2092f}
Provider=%Mfg%
;Uncomment this to run chkinf, or if you're signing the driver...
;CatalogFile=ekaio2wia.cat
DriverVer=10/12/2012,7.6.11.20
[DestinationDirs]
; By default, files will be copied to \windows\system32.
;DefaultDestDir=11
You need to reboot and install the unsigned driver as per the PC Pro guide
It worked a treat on this occasion. Let me know how you get on. Or if you need help, give me a call on +44 (0) 845 2233116
