Top 5 FAQs

I lost my software serial number.

Sign in to your online account via My McMillan. If you activated your software, your serial number will appear under "My Study Guides."

If you purchased your software direct from McMillan, you may also find your serial number under "My Order History" -- locate your order and click "View Details."

Can I get a discount on the AFH 1 Suite app if I already purchased GOLD or Advisor?

No. Since our apps are sold directly through iTunes or Google Play we are unable to offer discounts.

AFH 1 Suite app for Android requires OS 4.0 and up.

AFH 1 Suite app for iOS requires OS 6.0 and up.

Do you offer NCO DLC or SNCO DLC?

Our brand new NCOA courses are ready now! Visit CDC Central to place your order.

Our SNCOA courses are in the works. Sign up to be notified as soon as they’re ready.

Please note that the full text of these courses is not included in our study guides.

I receive the error "The application could not be installed because the installer file is damaged..."

Generally this error message is related to McAfee Antivirus blocking the installation of our program. If you are running McAfee, temporarily turn OFF "Real-Time Scanning" and try running our software installation again.

NOTE: Simply disabling McAfee from the task bar is not sufficient.

If your McAfee is expired or you do not intend to use McAfee, you must completely uninstall McAfee and then restart your computer.

If this solution doesn't work or you are not using McAfee, please contact Technical Support.

When will the 2019 AFH 1 study guides be available?

Unfortunately, the Air Force hasn't released the 2019 AFH 1 yet. As soon as it's out we'll rewrite our study guides to reflect the changes made.

Sign up at the Coming Soon page to receive an email as soon as our 2019 AFH 1 study guides are ready.

Better yet, preorder 2019 AFH 1 GOLD, AFH 1 Advisor or AFH 1 Bundle Up! and receive it the day we release it. If you don't already have it, you'll also get the 2017 version for free, to study now. Visit the Products page to find out more.
