Let me explain;
I Prepa3d v. 1,4, I bought AS2012, just one day after a few months when I clicked to start it you are no longer open;
then having the doubt that the installation file is damaged you, Iregained the AS2012 to solve the problem, just that i have not solved anything because it prevents me from opening it himself;
I known that ASN is not compatible Prepar3d v. 1,4 in fact i have not bought.
