Upgrade to 64 bit v6 from v5

Coming back to the fold

Okay…The last couple of weeks I have been recording on a laptop with v5 in a 32 bit OS. I now want to install v6 for 64 bit OS on the studio computer and give the laptop back to my daughter, really tired of listening to her complain. I dont see this upgrade path anywhere on the site…

Someone got a link?
