How do I tell Ax to use NET Framework version 4.5 or higher?

Hi,

I've got NET framework version 4.8.03761 on both my terminal server and AOS server. But Ax is still using 4.0 (which doesn't support usage of TLS 1.2 protocol).

I've already written ax32.exe.config file in C:\Program Files (x86)\Microsoft Dynamics AX\50\Client\Bin on the terminal server. File content is:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <startup useLegacyV2RuntimeActivationPolicy="true">
       <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5"/>
  </startup>
</configuration>

I did the same on the aos server (folder C:\Program Files\Microsoft Dynamics AX\50\Server\[my aos instance name]\Bin)

But seems like Ax keeps using version 4.0 of the NET Framework. And I need to make it use at least version 4.5 to be able to use the above mentioned TLS 1.2 protocol. 

Is there something I need to change on windows' regedit to achieve this? I've read a bunch of threads about this issue but none of them seems to have the complete answer. Please help.
