How to – Disable your Antivirus Software / Firewall Temporarily

If you are not able to install the software program/having difficulty installing updates or cannot connect to e-file website, your anti-virus software or firewall that you are running may be blocking TFP20.xx/Laser Link/Laser Link XL/ACA software program from installing.  It may be necessary for you to temporarily disable your firewall or anti-virus software to:

  1. Determine if this is what is causing the installation issues, and
  2. To connect to download the updates, etc.

Located on the Window Taskbar next to the clock in the lower right corner it will show the Firewalls and anti-virus software that are running on your computer. Most programs will allow you to right click on the icon and select 'Turn Off', or 'Disable'.  If you do not see this option you will need to open the firewall or anti-virus software and disable it. 

Note: If you need additional detailed instructions on how to disable or turn off a specific firewall or anti-virus software, we highly suggest you contact the anti-virus software company directly or your IT department for further assistance.

After you have installed the TFP20.xx/Laser Link/Laser Link XL/ACA software program we suggest you Enable the anti-virus again and set your UAC settings back to original setting.
