[GNC-dev] Windows build

[Robert Fewell]

Hi guys, looks like the windows build has been created in fro the last few
days, the last one being 10/05/2019 and looking at the logs it is failing
with a permission error. Could some one have a look and give it a kick.

Some thing I have noticed is the exe has increased in size again on the
28/04/2018, from 174M to 182M for the last successful build.

Also could the log files be pruned and may be some of the daily builds not
sure how many.

Regards,

      Bob
