Sorry. There are so many threads with ppl having 2017 install issues.
I most I always say to run Windows Update after doing the separate installs for the C Runtime and the dot NET.
Myself, I had installed that update on the 15th of OCT in 2015 !
The following “pinned” post (in this category) by SketchUp Team memeber Ty, does say that this update is needed.
If you search the forum, you’ll see that the KB2999226 update is mentioned frequently.

I’m not convinced of this. It works fine on my Win 8.1 machine.
I suggest you restore it. (Perhaps re-run the 2017 installer post KB2999226, and choose “Repair”.)
Glad it is working for you !
