64 to 34 bit

[duncbf1]

I have Vista OS and can no longer play old flight sims with my 64 bit system. Simply incompatible. Is there a way to convert to 32 and keep my computer comparably operable?

Buy the 32-bit vista, but you are better to buy the win7.

To be a bit clearer, there is no way to convert.
You can run programs in XP mode, which may help. You can also dual boot with XP 32-bit, provided you own that.
