#1139 Isses with missing nlog artifacts in CLI version

[horsemanza]

hi there,

am using the CLI version under Win2019 server, cause i don't have the desktop experience installed for 2019, so UI of naps2 will not work. i can't revert to desktop exp cause of constraints on this site. the naps2 console works fine, can see the printer, etc. but i get stack error about missing nlog extensions as following. have tried adding nlog manually but that is another can of worms since this is NOT a dev environment and i don't have time to build a custom fix. am wondering why does the naps2 deployment not work out of box, given i have right versions of .net installed, etc.

this scanner does not work with anything else, please help

error when running
C:\Program Files\NAPS2>naps2.console --device "Brother DCP-L2540DW series" -o "C:\users\XXX\scan.pdf" --driver wia --noprofile -v
Beginning scan...

The printer am trying to resolve wrt scanning:
Brother DCP-L2540DW series

TESTED IN OTHER WAYS?
It is scanning via scan profiles, if I do that via "Devices and printers"
...so device is installed fine, driver is there, etc.

My best guess is that your installation is broken (it can happen if you install both the .exe and .msi installers), try uninstalling and reinstalling NAPS2.

If that doesn't work, there's maaaybe a chance that an old version of NLog is installed in the GAC and causing conflicts. I'm not sure.
