I downloaded new wallet 4.0.0.4 for windows. I extracted all files. Now when I try to open it says something like "Error can't find libwinpthread-1.dll. Reinstalling may help fix this". Reinstalled. and same thing. please help. kind of frustrating.

I am currently using 4.0.0.3 wallet. is the new update needed to sync to block after february 2018?
