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.

Do you offer Airmen Leadership School (ALS) Course 00003 and Noncommissioned Office Academy (NCOA) Course 00015?

ALS courses 00003A and 00003B are available on CDC Advisor or CDC GOLD.

We take the same Self-Test Questions and Unit Review Exercises from the courses issued by the Air Force. We do not write additional questions. The text of these courses is not included.

You may choose one course with your purchase. To study a second course, you can purchase an unlock code for only $19.95 via CDC Central.

If you enrolled in the new NCO DLC, your course materials are available only on Blackboard at Air University. We currently do not have plans to offer this course at this time.
