CS5 is a 15-year-old, unsupported product that's way beyond its 'replace me' date. Even if you could install it on a new machine and operating system for which it was never intended, the aged out activation servers are no longer fully functional. Nobody can guarantee anything.
Best advice, replace CS5 with modern software that's fully supported & compatible with your new equipment.
