X6.1 Update Silent Install container.htm popup ?

I built a batch script to silently install X6.1 Update, X6.2 Update and Suite X6.2 - Hotfix 1, But I found when you try to silent install of X6.1 Update either by using the CDGSX6Update_1.exe /s or extracting and running setup.exe /qn it displays the following web page popup with the following :-

Then the X6.1 Update just stops and even if you press close on the dialog box the update appears to install but when you open and check the build number in Corel Draw X6 the X6.1 update appears not to updated the build number from 16.0.0.707 to 16.1.0.843.

Anyone have an  idea how to stop this popup and silently install X6.1 Update ?.
