I installed coino qt but it is out of synk always.
Why do you think it never synks ?
Make sure your date/time is accurate. Sync up with internet time, if it's not correct the wallets won't sync up properly.
Also make sure there are no firewalls in the way.
My software didn't prompt me, it just blocked it, I had to manually enable connections/allow, etc.
There is a network indicator icon bottom right of the coino-qt program that show network connectivity - if there is nothing, then no connections, not syncing.
If I were home I'd post a screenshot, I'm out atm...
