Make CRM Solution backword compatible, From 2016 to 2015

Hi:

I am exporting solution from Dynamic CRM 2016 and I have to import solution to Dynamic CRM 2015.

In other words, I have to make a solution that should be compatible with older versions.

When I import solution to Dynamic CRM 2015, I have to face following errors.

I already have imported solution freshly downloded from web,

Downloaded From Here Here for 2013/2015/2016

it is imported successfully, and

after this If i import solution that I have exported from CRM 2016, This error message Window is shown.

Is there any possible solution?
