When trying to install aerial photography for Quickmap Version 8, you may get this error:
The Air Photo install requires Quickmap Version 6 or higher to be installed.
You must install Quickmap Version 6 or higher first, before running this Air Photo setup program.
This happens because the Air Photo installer was created before Quickmap Version 8, which requires an update to the Air Photo installer to work with Quickmap Version 8.
To fix this, update the Air Photo installer using these instructions.
