OK! Has anyone actually gotten the scanning working under Windows XP? (the one button touch scanning) Scanning works under all programs, but I would like to use VistaScan. I know that the US site tries to make you buy the drivers, but I downloaded all the appropriate files from the UK site. First I installed 3.73 from the Disk, then 3.75 which is the Win2k drivers. The link test worked, but one button still didn't work. I upped the driver to 3.82 (Winxp) and then no software would run at all. I manually changed to the other driver that was packaged with 3.75 or 3.82 or whatever. Nothing seems to be working. It sucks because I have work to do. Anyone experience the same problems? Thanks in advance!

I never got mine to work with any software other than microsoft paint when I had windows xp. xp crashed my computer, so i'm back to windows me
I tried downloading updated drivers, but there were none available for xp, so unless recent updates have been released, i don't think you can use vistascan.

give up on the 3400 and don't buy their stupid $32 cd. Junk it and make Umax the last scanner you ever own. The 3400 was my 2nd Umax product but since the company got so tight I bought a Visioneer at Office Depot for $79.00 with twice the features and none of the problems. Very high resolution. If Umax won't support you why should you support them?

I think that I agree with bbromely. I e-mailed umax and have yet to get a reply, so no more umax

While trying to get the scanner to work under Windows XP is, at best, a frustrating experience, it can be done.

Go to Start -- Programs -- Vista Scan -- Vista Scan
Right click on the icon and select Properties

Click on the Compatability Tag

Select Windows 98/ME

This should enable you to use the scanner and copier functions but will not activiate the power buttons. I found the folks at UMAX to be cooperative but they couldn't get the darned program to work under XP.

I've tried getting a buddy's 3450 to work under XP and it just ain't happening. I downloaded a utility update from Umax that you're supposed to install over their software and it doesn't do a bloody thing. I also change the compatability mode as the pervious poster suggested. Results: no joy.

The crap works just fine on one of my 98 machines. I'm going to recommend to my friend that he relegate this to the nearest garbage can and buy a scanner from another manufacturer.

In case anyone is interested I got this bloody thing to work. There is a technote at http://www.umax.com/support/knowledge/search.jsp?docs=SC00305&SRCHkeywords=scanner

You have to choose USB driver as the driver when going through the fix and you need to go to VistaScan and VistaShuttle and under Properties select 98/Me combatablity. The down side is this will take the scanner off the Scanners and Camera List under My Computer. But you will at least be able to use Umax's crappy Software. I have a MFP so I will set the 3400 to use the software and scanner with my Brother MFP otherwise.

John Rene had it perfect. Follow that link. Worked like a charm for me.
