Bridge on my old PC

Hi,

I usually use adobe CC on my desktop computer, on win10 I think, no problem.
At the moment, I'm on holidays, and, I took an old laptop to work (just a bit) . It runs win8.1. That laptop runs a copy of PS and LR. It's only used once a year... pricisely during my holidays.
But this year, I need to install Bridge and AI... Unfortunaletly, I cannot install them bescause the new version seems to accept only win7 and Win10...

I hope i'm on the right group.
Can someone help me ?

Thanks,
Chris
