Some programms cannot connect to the internet

Question

Hi!
I have recently bought a new laptop with windows 8,1. Some of the programms that i mainly download from the internet and not from the store say that cannot connect to the internet. But i have internet... and all the other programms works correctly. I tried
to switch off windows firewall and windows defender but the problem is the same. So what can i do about that?

cannot connect to the internet.
Often that is just a misleading interpretation of "cannot do a DNS lookup fast enough to suit the program that wants one done" and further that the network topology is probably such that the program thinks it is on a LAN and therefore expecting
LAN level response time (e.g. you have it connected to a router with a local address for your DNS server.)
A workaround for such a scenario is making sure that the dnscache contains the full lookup that the program wants.  E.g. you can use  ipconfig /flushdns  then ping -n 1 -w 1 <problem hostname> then ipconfig /displaydns to see how much
time you have to use it (e.g. look at the Time To Live values, which are given as seconds before the entry will be removed from the dnscache.)
Good luck
