please always use the latest available version of that
openvas-check-setup. The current version 2.3.3 is available here:

In this case it is just a short info if you want to use the Nmap NSE
scripts during scans. Running nmap 6.4.7 or even 7.0.x for normal scans
is absolutely fine and supported.

Which is absolutely fine. OpenVAS7 is end of life since a few months and
you shouldn't and can't use it anymore. Btw. the correct install
instructions for recent OpenVAS versions are available directly here:

http://www.openvas.org/install-source.html

which is linked on www.openvas.org -> Try out OpenVAS -> Install from Source

Things can change, see:

--------------------------------------------------------------------
The default setting for the Alive-Test changes from ICMP&TCP&ARP to just
ICMP. Hence it can happen that results change for some of your Tasks
because some systems are not regarded as alive anymore. But in most
cases where larger IP ranges are scanned the scan duration will
significantly drop down while getting the same results. However, you do
not need to change a Scan Configuration or Task to get back to the
previous state, you just need to adjust the Alive-Test method for the
respective Target.

and this is exactly your issue here and can be solved by the hint posted
previously:

- If your system is not answering to ICMP requests the "Alive Test"
option of your Target configuration might be another pitfall:
http://docs.greenbone.net/GSM-Manual/gos-3.1/en/scanning.html#creating-a-target

Either configure your system to answer to ICMP requests or configure the
"Alive Test" options accordingly.
