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.

Installing a working ASPI layer For years people have had various problems with the so called ASPI layer, which is required by many Windows CD-R software’s. This article aims to successfully install a good and working ASPI setup.
What is ASPI? The term "ASPI" stands for Advanced SCSI Programming Interface. It’s a universal driver layer that operates in between software and the CD-R hardware. It is often referred as 'ASPI layer', ‘ASPI driver’, 'ASPI Interface', which are all synonymous terms for the same thing. Windows 95/98/ME ships with a poorly implemented ASPI layer, while NT/2000/XP has no ASPI layer built in. You can check your current ASPI setup by using the ASPICHK tool that comes with the Adaptec ASPI distribution.
Many software titles install their own drivers to the operating system and therefore do not need an ASPI layer. Such software titles include CloneCD, DiscJugger, GEAR, BlindWrite and many others. On the other hand there is a large number of software that require an ASPI driver installed: Exact Audio Copy, Feurio!, BurnAtOnce, CD-R Indetifier, and so on. Nero Burning ROM comes with it’s own ASPI layer that other software can utilize too.
The symptoms of ASPI related problems Problems that may occur if there is no proper ASPI setup:
-The CD/DVD devices are not detected by the software -The CD/DVD devices don’t operate correctly with some program
There are also some reports on the Internet of the ASPI layer affecting the performance of a program (like audio ripping quality) but they have not been properly verified.
Solution 1: Get the latest Adaptec ASPI layer Since the version Adaptec has been offering their drives freely for public. Their drivers should operate in any Windows version, including XP. There are however various reports of problems with these drivers. I tested Adaptec’s ASPI 4.72a2 in my computer, but programs utilizing it recognized only my SCSI connected CD drives - the IDE devices were not detected.
After downloading the EXE file, run it. The program asks for a destination folder, and unzips the contents there. Use, for example, C:\ASPI\ for the folder.
Next open the C:\ASPI\ folder using the Windows Explorer. Run aspichk (or aspichk.exe) and you will see if Adaptec ASPI verification can find ASPI drivers on your computer. If it says "ASPI is properly installed and fully operational" your ASPI drivers should be OK. If on the other hand it says "ERROR: ASPI is not properly installed", you need to install ASPI drivers.
To (re)install the Adaptec ASPI drivers, run aspiinst (or aspiinst.exe) and click Install. After the installation you should restart Windows, and run aspichk. You should then see the different ASPI driver versions listed, and the box at the bottom should read "ASPI is properly installed and fully operational".
Solution 2: Get the Nero ASPI by Ahead Software Ahead software also offers their ASPI layers free. They also promise support for USB/FireWire devices. Most programs should operate with Ahead’s ASPI, and there are many positive reports about the performance of this driver.
We on the other hand had a slight issue with Ahead ASPI. The Feurio! audio CD recording software wasn’t always able to lock the CD-R drive during the burning process.
Solution 3: ForceASPI ForceASPI is based on older Adaptec ASPI 4.60(1021) version. This version of Adaptec ASPI refuses to install if there are no Adaptec products installed on the computer (Software or hardware), but the ForceASPI package solves this issue by inserting the drivers to the operating system with it’s own installer script.
Adaptec ASPI doesn’t promise Windows 2000 or XP compliancy for the driver version 4.60, but public experience is that they work very well, even in Windows XP. On our test bench computer the ForceASPI was the best solution as an ASPI driver. It works flawlessly in every program tested.
1. Start -> Click Run 2. Enter msconfig and click ok 3. Click Startup tab 4. Uncheck program that you don't want to startup You can disable programs that you don't want automatically load when you start 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".
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.
