Please Note: This issue will be fixed in version 15.1 .1.
For this workaround to work, you must have .Net 4.5 or later installed for this to work.
This workaround reduces the security of your system as all protocols are open for use by all .Net applications.
In order to access a server which only support TSL 1.1 or 1.2, you need to add the following entries into your Windows registry:
