1. You are the installer: extract the entire contents of the zip file to a folder of your choice (e.g., C:\ACARS).

2. You can safely ignore any browser messages that the download was blocked - this is a false positive. In Chrome select Keep rather than Discard.

3. Some users report the need to Run as Administrator.

4. Antivirus softare may need to be temporarily disabled, and/or set to ignore fsacars.exe

5. Web blocking software (eg., Trend Micro) users MUST add fdxva.org to the exception list.

6. Allow acars to update, if necessary - Run as Administrator.

7. First time setup: go to the Settings tab and enter the same callsign and password as the website. Use the Verify button to be sure it's correct.
