Can't install any of cuda toolkit version!

I had cuda toolkit 10.2 installed and worked since year.
After I decided to update it, did find out that no version of cuda toolkit can be installed due to Nsight VS integration problems.
I use VS Community 16.5.8, Windows10, GF 1050Ti
Why is this and how to fix it ? I havnt had any issues before.
Finally i did install cuda toolkit 11.0 (unchecked nsight install) because I want to use it with tensorflow but I need and VS nsight installed too.
I did try NV Nsight stand alone installer but it tells me that I “Must correct or remove” VS Commnity.
My VS Community is up to date !
