Before Installing your Program

It is critical that you do the following before installing your program:

  1. Turn ON your firewall software
  2. Turn ON firewall alerts
  3. If prompted by your firewall, read dialog carefully and “Allow” or “Unblock” safe files
  4. Some firewalls may prompt you to allow additional files. You must allow these additional files as well.
    • Note: Proper permissions must be set for the Users to be able to update the program periodically as needed
  5. Users must be local administrators to their PC
    • Note: When the user accesses Federal and State Efiling successfully and selects their form then clicks on Accept the program will communicate with the Aatrix website.
    • Note: At that time Aatrix will determine where the users is at with their Forms and determine if an Update is needed. Aatrix will prompt to do an Automatic Update.
    • Note: If the user selects Automatic Update but does not retain the right to install programs it will fail and can corrupt the Aatrix program.

Already Installed Programs

If you have already installed the particular program and are unable to run it, you need to set your firewall to allow the following files to run using HTTP on port 80 to http://updates.aatrix.com.The Firewall must also allow password protected encrypted zip files


Please setup the following Internet & Firewall permissions:

  1. In Internet Options on the Security tab
    • Add the web address for https://sage100erp.aatrix.com as a trusted website
  2. On the Privacy tab, click on Sites button and allow the following websites:
    • aatrix.com
    • aatrixforms.exe
    • updater.exe
    • updater2.exe
  3. On the Advanced tab, under Security section, please select the following:
    • TLS 1.0
    • TLS 1.1
    • TLS 1.2

If error still persists:

  1. Verify firewall settings:
    • Aatrix Forms Updater uses standard HTTP port 80 to access the site http://updates.aatrix.com and must also allow password protected encrypted ZIP files.
    • Aatrix Forms uses the following programs to access the Internet.
    • For Updating using HTTP on port 80 to http://updates.aatrix.com:
      • aatrixforms.exe
      • updater.exe
      • updater2.exe
    • For eFiling & web service connections, allow the following files to run using secure HTTP on Port 443 and 80 to
