Hi reggiebrooks,
I checked windows 7 64bit on my old laptop for me it's OK. Could You run THE IMPOSSIBLE as administrator?
Or send me message: airempl@gmail.com, I could create a "custom build" for you, maybe it will help.

UPDATE: I will soon (1-7 days) update IMPOSSIBLE + engine (maybe it will help).
UPDATE 2: And maybe You could check Steam version? https://itch.io/t/67604/how-to-get-a-steam-key-from-your-itchio-purchase
