After downloading LKM files, they are saved as ZIP! Why? Print
If your operating system, like VISTA, is saving LKM files as ZIP files, no problems.
Download them, and then rename them back to LKM.

you download ALPS.LKM
Vista is saving it as ALPS.ZIP
After download, you rename the file as ALPS.LKM

LKM files are in fact ZIP files, but LK8000 need .LKM suffix.

It is also possible to reconfigure something inside Vista to make it save correctly.
But I don't see it as a problem to rename some file once upon a time, right?
