Can you try with this test version? naps2-7.0b3-testwia.zip

And then, whether or not it works, can you take the errorlog.txt file from the Data folder and attach it here?

Thanks, can you try selecting "1.0" for "Wia Version" in the Advanced profile settings window? Doesn't matter if it's the test version or the normal NAPS2 installation. If that fails too I'd like to see the error log.

Hi, if you're still interested in trying to fix this, I'm circling back to this as I got my hands on a fi-6130Z, though I can't reproduce the issue. What driver version do you have installed? You can find it in Device Manager.
