Hello all

i am currently running zen cart 1.3.9h with apache 2.2 Mysql 5.5 and php 5.2.17 on windows XP

i am planning on upgrading to 1.5 the latest zen cart release.
I would like to upgrade my php 5.2.17 to the recommended 5.3.8.
However I have no idea how to do this

If someone could advise me please would really appreciate, then I can continue through the checlist to upgrade zen cart.

Thanks
