DateControl Plugin from Einhugur Not Loading

I love Einhugur’s DateControl plugin. The later version works beautifully with later versions of Xojo. However, I cannot get the earlier versions (notably the version for use with versions before 2017 such as 2014r3.2, for which I have a licence) to load the appropriate version of the control. I have copied it into the Plugins folder, as required, but to no avail. Can anyone advise, please?

You should talk to Bjorn about that.

As far as I know the plugin format changed at one point, so you need to use an older version. Ask Bjorn for what version best to use.
