Open up google maps and go into settings. Make sure Use GPS is checked. If not, check it. then click on GPS settings below "Use GPS" and it should say Managed by Windows.
If that does not work click on Set Manually and COM Port below that. Choose COM 4 and then OK. That should do it.

IMHO, Quick GPS helps but does not do anything if you cant even get a gps lock. Its more of an enhancement than a substitute.
