I'm running Windows XP. Whenever I use the scanner, I get two errors. First: "Tvichw32 Driver Open Error", then "Cannot Load ASPI Layer Driver". The scanner will then perform scanning or copying just fine, but it won't work from within some other graphics/photo programs. I've deleted and reinstalled twice, but still the same errors.

Re: Tvichw32 Driver Open Error
Hello Aunt Pat
(01) Is this scanner "new" to the computer it is installed on now (where you're experiencing these issues)?
(02) Did this problem show up w/out apparent cause or relation to any recent changes on your system (e.g. New hardware or software installed, updated, upgraded or removed; system crash; computer repair; etc.)?
(03) Did the problem appear soon after a change to your system? (see above examples)
There are many references to this issue on the Internet. I've listed a few here. You can find many more, if you like, by performing search engine queries.
THIS links to a Roxio forum thread regarding this issue. (Even if you aren't using Roxio software, the information here could be relevant to your issue.)
THIS link will explain a bit about what TVICHW32 driver is.
I'd reinstall the ASPI drivers. A driver file may have become corrupted. (Assuming you'd been using this scanner successfully on this system until recently.)
You can find links for Adaptec's ASPI drivers on their web site HERE. They also have an ASPI version checker you can run to find out what verison is installed on your computer.

By disabling these programs will help your computer startup faster. 5. Click Ok and restart Now you should notice that your computer startup faster.
My Hot Tips to Make Your Computer Faster: * Regularly check your startup folder to prevent malicious programs installed itself without your knowledge. * Delete the temporary files from Temp folder (Start > Run > %temp% > delete all files). * Upgrade your RAM to makes your computer boot faster : ) I hope this helps you to make your computer faster..
The LS2000 is older than XP and has some fairly tight requirements to work. The recommended SCSI adapter is an Adaptec 2906, and you will probably need to backrev the ASPI layer driver files to version 4.7 (available on adaptec.com site). You may need to boot in Safe Mode to remove the later versions of the ASPI files before you can install the 4.7 files. You will also need to update your Nikon Scan software to version 3.1.2, available online by googling "nikon scan 3.1.2".
Are you using a Kofax SCSI card or an normal SCSI controller like Adaptec?
By using a normal SCSI controller, is there an ASPI driver problem after a
WIN XP update? After an update check the ASPI dlls in \sytem32. They should be version
4.71 or higher.
Check the SCSI connector pins and the terminator. If available change the cable.
Scanner check: Is the green lamp (Ready) on or is the red lamp (Error) on?
- green lamp on: the internal self test is ok, but the internal SCSI interface may possibly faulty.
- red lamp on: the internal selftest detect an error. It's possible that the DC/DC power board, the CPU board or the power supply inside the scanner is defective. After reassembling the front side camera you will see at the bottom a PCA board with some LEDs whitch indicate by red light the different voltages when power is on. You find the different voltages printed at the PCA close to the LEDs. In case on or more LEDs don't shine the according DC/DC transformer on the PCA is defective. Futher you see LEDs at the camera PCAs. They should be on too.
In case the CPU board has an defect you must have an special Kodak activation tool to unlock an new or used CPU board after exchange.
Windows XP supports Astra
610p with its own WIA driver. So to install the WIA driver open the
Windows XP controll panel “Scanners and Cameras. Select the command “Add” and as Manufacturer select “Umax Data Systems”.
Follow onscreen step-by-step instructions to complete the installation for Astra 610P scanner.
I have the same problem (on XP, Nikon Scan 3.1.2) ... IF I turn the scanner on before the computer (or turn the scanner on and then reboot) then Nikon Scan recognizes it. Can't say I'm happy with the solution, but it works consistently for me.
I know some devices may not work properly or will not work period if your running a 64 Bit processor. I would recommend to contact the manufacture of your scanner & verify this. Possibly they may have 64bit drivers. Hope this was any help to you.
