When it comes to printers they have many problems.
Lately my office multifunctional all in one Scanner, Copier, Printer Samsung CLX 2160 after a malfunction
brought this to the screen:
OEMCFG.dll file is missing Samsung needs this file
so there it was and my Scanner just vanished from My Computer interface
after many tries the solution was quite simple. Who would have ever thought?
Browse to location C:\Windows\Twain_32\Samsung\CLX216X\OEMCFG.dll
and select it
There you go
Scanner working like a charm.
