What version of dot net framework does Adobe Framemaker 2019 need?

[tekwrite2013]

I had dot net 4.6.1 installed but the trial for Framemaker 2019 would not install. I tried to install 4.72 and it uninstalled my 4.6.1 and crashed and deleted all my restore points!

So I assume it needs a version above 4.6.1?
