I was a bit stunned when I attempt to deploy the vSphere Replication Appliance on a new v6.7 cluster.
The Next button on the very first page where you select the template files just never turned blue (it always stayed grey) after selecting the files, just like if I did not selected all the files or the template is incompatible or corrupted.
No matter what I tried, it just stayed that way – trying to import the same template in a v6.5 cluster worked like a charm.
It turned out to be a bug on the initial v22.214.171.12400 release. After upgrading the vCenter appliance to 126.96.36.19900, the problem was resolved.
