hi everyone, i need some help   to be more exact i need php 4.2.2 for testing purposes [because a very nice university haven't got the time to update it and i must use this version or less]   so i am thinking about 2 sollutions   1- where can i download an old version of uniserver 2a1 or 2a2?    will it run on vista?   2- can i modify any current version of uniserver to downgrade php to 4.2.2                [i have managed to get the binaries for this php version from their website]     thank you in advance for your help
