Re: filmscanners: Nikon Scan 3.1 / Windows 2000: "Could not openNikon Scan 3.1 data source"

[Svante Kleist <svante+filmscanners@nemesis.se>]

Thanks for your answer Tom, and other helpful people
who have answered me here on the list and in private.

Following your advice, I've now de-installed all software
related to the LS 4000 and the 1394 card, including running RegSweeper.exe.

Then re-installed everything paying close attention
to the specified steps in the User's Manual.

Same results, i.e. "Could not open Nikon Scan 3.1 data source"
when the stand-alone application is launched.

(Note that I'm succesfully using the 1394 card with a WebCam,
unconnected now of course, I've even un-installed its software).

I'm now beginning to suspect the install program for "Nikon Scan 3.1".
Since no installation instructions were provided,
I simply double-clicked on the shortcut to "Disk1\Setup.exe"
(this shortcut was named "Verknüpfung mit Setup" by the way ;-)

At the end of "Readme.wri" is listed "TWAIN_32.DLL" (obviously in of the 
.cab files).
The only file named so on my computer is "C:\WINNT\twain_32.dll",
44 816 bytes, version 1.7.0.0, i.e. the one provided with Windows 2000.

==> Shouldn't "TWAIN_32.DLL" from the "Nikon Scan 3.1" distribution
    end up somewhere on my disk after installation?

==> And what about "Twunk_32.exe" in the folder "NScan31"? The one in
    "C:\WINNT" is also the Windows 2000 original.

When I try to acquire from TWAIN in other applications, I note that
no TWAIN sources are listed. Maybe this has something to do with
the "bugcheck" that crashes Windows when I start VueScan?

As you understand I'm beginning to feel quite desperate.
At all means, I want to avoid a complete re-install of Windows.

Please Please Please try to set me on the track!
