First timers - Trial or Purchase

Once the process is complete, you will receive an email with the subject line: APCC Email Authorization Sent: (your email address displayed). If you do not complete this step, you will not receive a license key (permanent or trial). 

APCC License was Issued Previously and APCC is Already Installed

• Beginning with version 1.9.x,  APCC will query the license key of your existing copy of APCC to determine the date the license was issued.
• If your license was issued within one year prior to the release date of the new version, all of the new features and updates will be activated following the software installation. 
• If your license date is older than one year prior to the release date of the new version, then only the bug fixes and minor updates will be activated. In order to activate the new features and upgrades, you will need to purchase a one-year subscription. Please refer to the Order and FAQ tabs of the APCC webpage for more information and review the version history to see what features are included in the most recent version.

Important Installation Information

Do you have to uninstall previous versions?  If your installed version is 1.8.8.17 or earlier, you must UNINSTALL all previous version of APCC. This is required due to the new version of the Eltima Virtual Ports Driver that will be installed. You will NOT lose your settings, models, horizon or meridian limits. If you have a later version, you can install over the previous version.

Be patient as virtual ports load.  Occasionally, users have had difficulty setting up their virtual ports that we think may be linked to disturbing the installation process when the virtual port driver is installed. Please read and heed this warning. Near the end of the software installation process, a black DOS-style command window will open. DO NOT interfere with this command window!  Don't touch anything on your computer including the mouse or keyboard while this window is up. Doing so may cause a failure of the virtual port system. Please be patient.
