Actually webmedic using the oempnpdriverspath doesn't work for everyone. It didn't work for until I edited DOSNET.INF, DRVINDEX.INF & TXTSETUP.SIF. What works for you might not work for someone else thats why its needed.
I understand what this does. Thanks even though I don't use vbs scripts but this information is very helpful. I usually use sfx rar files, reg files and batch files.
