Installing Julia BinaryBuilder.jl packages on Windows 7

I am having difficulty installing various Julia packages on my Windows 7 laptop. When trying to add certain packages I receive the following error:

(v1.3) pkg> add MbedTLS
  Updating registry at `C:\Users\uname\.julia\registries\General`
  Updating git-repo `https://github.com/JuliaRegistries/General.git`
 Resolving package versions...
ERROR: Unable to automatically install 'MbedTLS' from 'C:\Users\uname\.julia\packages\MbedTLS_jll\wUtL4\Artifacts.toml'

Several packages install happily, and I think I've narrowed it down to those that are supplied via BinaryBuilder.jl, such as MbedTLS, Arpack, OpenSpecFun. If I try to install any packages that have any such packages as a dependency I get the same error message when it hits one of these (initially encountered when I was trying to install Genie.

I am using the latest Julia (1.3.1), although I encountered the same issue previously in 1.2 - I managed to fix things eventually in that case, and tried a similar approach (manually downloading and placing in packages folder) but have not been able to fix things in this instance (although I confess that my notes were a little lacking so can't be certain I'm doing the correct thing). The various packages seem to exist in ...\.julia\packages\ (although not in .julia\compiled), but julia complains whenever I try to add them to some environment.

I don't think I understand julia's package system well enough to see quite what is going on here. I have seen other people with similar issues but not found anything yet which has worked - any help would be much appreciated!

This usually is due to an issue with your powershell installation, which is what we use to download these binaries in Julia 1.3 and 1.4. In particular, most of the internet (including GitHub, where most of our binaries are hosted) disabled SSL v3, TLS 1.0, and TLS 1.1 in 2018. Windows 7 is old enough that it doesn't speak TLS 1.2+ natively; instead you must install two packages:

This is necessary on Windows 7, but not on Windows 10. For more instructions, you can read the Julia platform specific instructions: https://julialang.org/downloads/platform/
