I had to buy a new computer and now can't get my CS3 with CS5 upgrade to work on windows 8.1. What can I do to get them to load and work?

I can load CS3, but it won't let me register it and I can load CS5 upgrade, but when I open CS5 it shows fault and closes. What can I do to get these programs to work on my new computer?
Registration has always been optional, so there is no point in trying. Those pages on the Adobe site are long gone. CS5 crashing is another matter, but without some crash logs and more detailed system information nobody can realyl know. This could be a mundane permissions issue on some files, could be a crash with the hardware acceleration stuff but just the same could be the activation system failing. Impossible to tell based on your limited information.
