I have installed VS Professional 2019 v. 16.10.1 .
I could install Microsoft Analysis Projects extension but the installation of the SQL Server Integration Services Extension failed.
I have restarted twice the workstation, but every attempt to install the extension starts – as displayed in the screenshot - with no other option than closing the installation. ( the checkbox can not be selected).

In installer I saw "Setup completed with warnings"...
this is second time I installed my laptop.. first time also I saw the same issue , thats why re-installed VS2019 V16.10.1..
