Thank you for posting shots of this! This is the first time I'm seeing it, so this helps a lot! ^^ Anyways, the third screenshot... That is the "Do you agree to our terms?" box. Select the top selection, then the "次 >" (Next) button should be clickable.
After that there will be a different window that asks you to select where to install the game.
If the game starts for you, even if it is in Japanese, then that's good!! Now you'll just need the Windows 10 English patch. ^^

Look for the ones that end with "win10" in the filenames.
PAY ATTENTION!!! There are TWO DIFFERENT VERSIONS of the CGs! One is JUST the buttons and menu in English, and the other one is a FULLSET, which includes the buttons AND uncensored smexy scenes. Choose ONE, not BOTH.
So, you'll end up with two files:
nss-fullpatchver2.4win10.npa ...and either
cg-buttonspatchwin10.npa -OR- cg-fullpatchwin10.npa
Afterwards those two files will need to be renamed.
nss-fullpatchver2.4win10.npa >> nss-patch.npa
Then your preferred CG file will be: cg-patch.npa
