How to instally multiple copies and versions of ETAP?

[himmelstern]

versions of etap work simultaniusly, but I don't uderstand to do that, somethimes it creates conflicts with 12,5 and 14,1 version with installers.

even If you do some same calculations of previus versions of etap, results are different some times, for that reason is better to use the last version of it.

Dear Himmelstern
Based on your explanation on above, it seems that you have Etap 14.1 including the solution. Could you share it? thanks
