Technically speaking, monster sex only occurs for 3 out of 9 of the childhood friend's sex scenes (Reprises don't count, the final defilement is one sequence so I count that as one, and alternate scenes are distinct so count separately), but she also has one masturbation scene due to aphrodisiac. That's a ratio of 5 to 9 for scenes where the MC's body is physically involved, though it may differ on the girl, since I don't remember how the game handles 3 heart heroines.
No. In all of the monster + masturbation cases Clive is verbally assaulting the girl in question. When I said physically involved, I specifically meant that the MC's body could physically be seen in the art, and is doing sexual things directly to the girl. The MC's body is always technically physically present, but in the above mentioned cases rather than doing anything sexual himself Clive mouths off to decrease the girl's morale while his minions do her, and doesn't appear in the CG.
Idk if u still need the help, but Imma still tell u what I did. Instead of just opening the installer I first went to t he installer's properties and in compatibilty I ran it with windows vista. Hope it helps (if still needed)
