Hang on, what? You'd change the luminance target if the screen is too bright or too dark. Is that the case?
For the screen's coolness, you change the white temperature.
Darn it, you're right. My googling says that (weirdly) Adobe have continued support for Windows 7 64-bit, but stopped supporting Windows 8 a couple of years ago
I had Photoshop CC running just fine on Windows 7, so there is no reason it won't run on Windows 8.1.
Can you elaborate on the problem? What's happening, exactly?
Thanks.
Sometimes that means that your room lighting is too yellow. Could that be the case, or are you comfortable that it is nice and white (similar to daylight)?

Yep, I can help you create any of these. Just post your photo in this section. But make sure you read the Posting Guidelines first, they're so critical.
Any photos at all, as long as they show a range of colour.
For a true black-and-white just use my action. Otherwise, simple a Hue/Saturation layer with the Saturation slider dragged all the way to the left.
Without prints you can't know if your calibration is correct; and without confirmed calibration you can't upgrade your class. Please get those prints pronto.
