I downloaded both software versions, V32 and v31

However, V32 had only one file within it - an ISO file and v31 has three files within it.
How comes the difference?

Do i just burn all three files from v31 onto a blank cd and install?

I'm more confident about using V31 as i downloaded the mode 2 link where as 'appys' link on v32 release does not specifiy if it's mode 2 or 1.

Thanks for any help
