AFDP does not have it's own built in installer that places files where they are needed. You are required to put the data files into their proper places...

To make things easier for end users, many of the modelers have created their own installers using installation software tools.

However since many planes originate in other countries, the locales, folders, and data structures are different.

e. g. C:\Programme\Ipacs\Aerofly Deluxe Pro instead of C:\Program Files\Ipacs\Aerofly Deluxe Pro

Most of the installers have an elipsis or option to specify the target folder.

You should ALWAYS take advantage of that. Manually select the target folder.

However in some cases one installer may want to be pointed to the top level AFDP folder ( e.g. C:\Program Files\Ipacs\Aerofly Deluxe Pro ) while another may want to be pointed at the Aircraft folder... ( C:\Program Files\Ipacs\Aerofly Deluxe Pro\Aircraft )
