Trouble downloading older versions

[EL_10923656]

I have trouble with different versions on my school computers and on my own laptop. I myself have MathCad version 10.0 (free verion) and my school computers has 7.0. Now I can't open files on the older version that I have edited on my own laptop. Is there a way to download older versions of MathCad. I tried it from MathCad Express Free Download but there was no option to select older versions of mathcad to be downloaded.

Thank you in advance!

Is there a way to have both versions downloaded at the same computer. I tried to download the older version and it said that the other versio of this software needs to be deleted first.
