Quartus archive project from 13.0 does not load in 11.1

[Altera_Forum]

I have archived my Quartus project and generated a ".qar" file. When I restore the project in Quartus 13.0 everything works, but when I try to restore the project in Quartus 11.0 I am receiving an error. 

 If i copy the whole project folder from 13.0 and use load it in 11.0 on another computer it works fine but project folder is quite large so I would like to use the ".qar" file if possible.  attached is a picture of the error i am receiving.

Figured out the problem and how to solve it. 

 Need to ignore that error and just open Qsys, then generate, then try again to open the archive file. then compile the whole project. same steps i had to do in 13.0, quartus 13.0 just dont show that error.
