Why do you want to install an obsolete product?
Its EOL since 2017 and will be EOS sometime soon, if it already isnt.
That said, heres a link with all the install guides available online
I highly suggest however you look at another call recording solution thats still supported.
Cisco uses AQM for recording now, which is a calabrio OEM product. If your licensing is still under contract, you should be able to convert from mediasense to AQM recording licenses at no cost.
