WyUpadte unable for check updatesAnswered

Hello, I am registered user of WyUpdate.
I am starting today its use following the step-buy-step procedure as from https://wyday.com/wybuild/help/walkthrough.php

Currently I have checked until step 3H because I get error ("Error trying to save file: Error downloading "https://atcadsoftware.com/updates/wyserver.wys": )
I have tried to download manually the file wyserver.wys and it downloads ok 
https://atcadsoftware.com/updates/wyserver.wys

Also I have setup MIME types  
Can you help me to understand where am I wrong?
Thanks in advance
 

Answer

Use the .NET 4.0 version of wyUpdate. And make sure the TLS settings are correct (both for the server and the machine)

Sorry :"Use the .NET 4.0 version of wyUpdate"
I have downloaded latest version of wyBuild and I have applied the key. Is it correct?

Answer

In File → Properties you can choose which wyUpdate version you want use.
