Problem opening Cubase

Hi guys

I’m a newby and I have been using and trying to learn Cubase 10.5 with my steinberg. Everything was going smoothly but today it seems I cannot open any of my projects nor the program itself. When I try, I get a small window saying an element cannot be found (VCRUNTIME140_1.dll) and I should download the whole program again. Can anyone help me?

Thanks
Irene

Did you save the installer? Can you run a reinstall?
