i have 2 winbox.exe file with different size but have same version 2.2.16
downloaded from my router.. Mikrotik v.4.11 size 53KB, and from mikrotik.com download page 110KB..
my question is why their size’s different if they are same version? 
(sorry for my poor english 
)
maybe one is downloaded from pre-release version of RouterOS (just a guess)
but you can delete both of them and get new one, either from your router or from demo.mt.lv
i think i know why they are different…
winbox.exe file which downloaded from router have been upx-compressed…
and from mikrotik download page are not compressed…
am i wrong?
i just wondering if i got viruses on my system… hahahaha
thanks anyway…
