AAF from Avid is looking for a prproj file in AppData\Local\Temp folder with the same name as the AAF file itself.
I'm on a WIN 10 x64 machine running CC 2017.0.2
The AAF did open nicely on my laptop running CC 2015.2 so i installed 2015.4 on my main machine and it did open it. I then migrated the 2015 project to 2017 and it seemed ok.
Problem is, now i got another AAF and both 2017 and 2015 can't take it in. The 2015.2 on the laptop also has the same problem now.
I get "File Import Failure" and it asks for a prproj file in the Temp folder showing an Error stating that the project is damaged and cannot be opened.
