problems extracting rekord box download

Hello,

I am having problems  rekordbox software on my computer. I managed to download the software (32bit Windows) but when trying to extract the file it crashes. 

I am using an older computer: Dell desktop 2008 running Windows Vista.

I have bought a CDJ 350 and I probably will have to use an earlier version of Rekordbox so it can run on my computer. Can you help?

Many thanks

Charlie
