select / radio button - radioselection

as I select right?

so far I have everything installed first and copy and delete the version made ​​in retrospect!

I would like now but in the beginning the so select only installed what is needed to the particular version!

for example:
%appfolder%\ program name \ version (a) \ data \ ...
%Appfolder% \ program name \ version (b) \ data \ ....
&appfolder% \ program name \ version (c) \ data \ ....

radio button (12 buttons):
there is a radioselction (session variable) for version (a / b / c) and drive (C / D / E / F)
