SafeDesigner Version 4.3.1.4

I need the SafeDesigner Version 4.3.1.4 for an old projekt.
But this version is not available @ B&R Switzerland, Germany and Austria.
Is this version somewhere available?

The versions of SafeDESIGNER available from B&R can be found on the B&R Website here: Automation Studio SafeDESIGNER | B&R Industrial Automation

I would recommend using the latest version in your major revision line, in this case. 4.3.5.3
