Installation fails (win7)

When i try to install it gets stuck on CRT update. I have admin rights and i start install with the right click and “run as administrator”. I have tried to turn off f-secure (antivirus), but it doesnt help. Any help is very much appreciated ! OS is win7

download/install the mentioned Universal CRT hotfix directly from MS and run the SU setup again.

If i dowload that update directly and try to install it, thenit gets stuck, it will run forever…“searching updates”

than your systems seems to be flaky, run the Windows update first and restart Windows afterwards.
