How to install InDesign 2014

Hi,

One of our customers is using InDesign 2014, we already have our plugin ready for 2014 and my colleague want's to install 2014 now on his machine for demos and support. I assigned a team license to him, he installed the CC desktop application. But there we only see CC 2015 and no 2014. If I select 'Previous versions' in the filter, I seen an InDesign without version info. How do I install 2014 now?

Thanks

Klaus
