ur-rt2 installation error

After a PC format (running on Windows 10 pro 64 bit) I am trying to install the latest drivers for ur-rt2 (TOOLS_for_UR-RT2_V110_Win). After the installation begings I get the following message:
An error occurred during the installation of assembly 'Microsoft.VC80.CRT,type=“win32”,version =“8.0.50727.6195”,publicKeyToken=“1fc8b3b9a1e18e3b”,processorArchitecture=“amd64”. Please refer to Help and Support for more information.

I tried the steps described here to no avail (I indeed have the windows build 1803…)

I also tried installing the previous version of the ur-rt2 driver, again, the same problem appeared.

The audio has serious artifacts (clicks and pops now and then) which may have to do with the installation problem (I hope).

What should I do?

Silly as it was, seems to have been an antivirus issue. Once I whitelisted the installation folder it run normally.
