DAQExpress Connection Error or Offline Usage

Issue Details

• I'm working on a computer that is not connected to the internet. When I launch DAQExpress it does not open and displays following connection error, can I work offline with DAQExpress?

• Whenever I launch DAQExpress, I log in to my NI Account and then I see the below error message. How can I resolve this?

Solution

Offline Usage

1. Periodically offline: DAQExpress versions above 2.0:

• DAQExpress will ask you to log into your NI account during first start when internet connection is established.
• Otherwise connect your PC to the internet, launch DAQExpress and log in.
• After first launch and log in, it is possible to use DAQExpress offline for the next three months without a license. After this time, you will be asked to log in into your account again.

2. Offline: DAQExpress versions 2.0 and earlier:

• You can purchase a license of DAQExpress to activate it if you cannot access the internet periodically.

Connection Error

1. Verify that the PC has a stable internet connection.
2. If possible, disable any Anti-Virus or Firewall that could be inhibiting network communication.
3. Verify that DAQExpress is permitted to communicate using TCP/HTTPS on ports 433, 80, 3580 and 53.
4. Ensure that DAQExpress can reach the following URLs:
