Launching error message

[stgreer]

I just installed the demo SF-8.0.1r36(Nikon)_x64.exe on my Windows 7 (64) system. The program recognizes my scanner (Nikon Coolscan 4000 ED), but when I press the "start here" button, it says: "There was a problem starting your scanner. Please make sure the drivers are installed correctly. Exiting now..." I'm running on Firewire. I uninstalled and reinstalled the software, and made sure I booted again before testing each time. I sure would like to look at what this program can do. Any help would be appreciated.

Dear customer,

please follow this instruction to install the correct driver.

Kind regards,

I have installed this driver through the device manager: nksusb_ieee1394_lsi.inf.
Silverfast 8.0 lists my scanner on the launch screen, but when I click on "start", I get exactly the same message as before:
"There was a problem starting your scanner. Please make sure the drivers are installed correctly. Exiting now..."
I do have one other imaging device: a wireless HP print/scan/fax. But I have unplugged it and disabled it through device manager before attempting to launch Silverfast.
What should I try next?
Regards, Steve

Dear Steve,

That is strange.
Can you please try uninstalling the Nikon from the device manager.
When asked confirm that the drivers should be removed.
Afterwards try reinstalling the latest SilverFast update and test if the driver installs correctly now.


Kind regards,
Arne Ketelhohn.
