I've had the above on my computer for several years - seemed to work well at first, but over time it has gradually become more of a problem.
I wasted a fair bit of time yesterday scanning a number of documents - frequent crashes/freezes, distorted images - and decided I would uninstall the software and re-install it.
Nothing but trouble resulted. A combination of manual deletion and Revo Uninstaller eventually seemed to get rid of it. I downloaded the latest HP software, which is a complete package of some imaging suite as well as drivers. When I tried to install, it appeared to work, but left no desktop icon and no way to actually start the program. I downloaded an HP scanner doctor utility, which reported problems with Twain and told me to disconnect and reconnect my printer, with no effect.
I wonder if this is where the problems lie, in that there used to be an HP printer installed.
If I try to uninstall the scanner software from Control Panel, the entry under Programs is dead. If I re-run the installer and ask to uninstall, it just closes.
I have also tried to install from Safe Mode - no difference.
So I'm stuck with what looks like a partial installation of the software and no working scanner.
I'm seriously wondering if I should just buy another scanner.

And yes, Get a new Scanner/printer that does not use Twain. It always was a C-O-S even in the 16 bit days.

Thanks, Z. I take your point (and link) about Twain being a problem.
"Get a new Scanner/printer that does not use Twain."
I bought a stand-alone printer not that long ago and don't therefore want an all-in-one, just a dedicated scanner.
So how would I know if a scanner I was interested in buying doesn't use Twain? (I mean, I don't expect the spec to say, "This scanner does not use that C-O-S called Twain.")

Update:
I've discovered I can download a basic set of drivers which makes the scanner accessible from programs like Gimp, which I use for editing. From there I can specify the use of WIA drivers*. As this allows quite a few settings for resolution etc. I'm happy with that for now.
*Is this what Zero means - WIA, not TWAIN?

Yes thats what I meant. Twain more or less went west when scanners became USB connected, tho they hung on for a while.

Another update:
I found something useful to get rid of the last remnants of HP from my computer. There's a Microsoft facility which you can run from here:
tinyurl.com/9dfw4o4
It will scan for problems associated with programs that will not install or uninstall properly because of registry problems and deal with them. I found a lot of stuff that doesn't even appear in Control Panel and got rid.
