[R] problem downloading R

[Dick Mathews]

I am trying to download the Windows version of R. This computer is Win7, 
I do have Win10 computers also.

Tried R4.0.4, got message these files are corrupted.

Then tried R4.0.3, got same message as above.

Tried the next, R4.0.2, got same message.

I checked to see if I was downloading the proper version, seems okay.

What is the problem? Can anybody help me with this?
