Oh, I see what you mean.
That's right, I do not provide "support" neither for Linux nor Windows installation, and in fact you won't need it. NL5 is just one file, nl5.exe. There are no dlls hidden in system directories or anywhere else. What you need is copy nl5.exe on hard drive, or even run it from any media, like flash drive or network. For updates or new versions simply replace nl5.exe with a new one.
For Wine, you have to know how to run windows applications there. I can't help with that, I'm not using Linux, sorry!
As for technical support, if Manual or Help reference does not help, you can use NL5 forum, submit question at nl5 website contact page, or better drop email at email@example.com
. You can call 970-414-0515 as well: this is Sidelinesoft "official" phone, but it's not always available.
