Hello.
First of all, I don’t want to miss the opportunity to congratulate you on your D5 render application, it is great.
Secondly, I have a problem with the 2.6 update. The download is blocked and I can’t update it.
Greetings
Sorry for your issue. 
Did any pop-up window show on your screen? And please check your network speed, if you have a slower network speed, we recommend that you download the installer directly from our official website and install it.
