The iRacing.com system software requires access to the internet enabling communication between your computer and the iRacing.com servers. This communication is necessary for operation of the iRacing service; it allows your computer to join online sessions, check for updates to the iRacing software, and it enables other member website functionality.
You may see a blank page or get an error when updating if these executables are blocked by your firewall. Unless you specified otherwise, the default location for your iRacing.com software is your C:\Program Files\iRacing folder. If you are using a 64bit version of either Windows 7, Windows Vista or Windows XP, the default installation folder is C:\Program Files (x86)\iRacing.
Some common firewalls are NOD32 v2.x, NOD32 v3.x, NetNanny, Norton Internet Security, Norton 360, and Avast. If you see an error during the next step, or if the update in the next step does not work, it is likely that the problem can be fixed by adding the following executable files to the list of executables that your firewall allows to communicate over the internet.
Simply disabling the firewall will not automatically allow the necessary program files access to the internet. This has to be accomplished by allowing the following files as exceptions in your particular firewall software. Refer to your firewall instructions or to one of the links below to find the directions for doing so.
C:\Program Files\iRacing\iRacingService.exe
C:\Program Files\iRacing\iRacingSim.exe
C:\Program Files\iRacing\iRacingLocalserver.exe
C:\Program Files\iRacing\iRacingChat.exe
C:\Program Files\iRacing\iRacingLauncher.exe
C:\Program Files\iRacing\updater\iRacingUpdater.exe
