Do I need to purchase 2 different fortran compilers?

Hello,

I am using two FEA software packages that I need to develop user subroutines. The products and their requirements are as follows:

ABAQUS: Intel Visual Fortran 10.1 and 11.1
RADIOSS: Intel Fortran Compiler 10.0.027

Can one of these work for both ABAQUS and RADIOSS or do I need to purchase different compilers for each?

Thank you very much.
