CS4 is the earliest version that has focus stacking.
I use CombineZP. The author's web pages have been dark for about a year and there is no activity in his Yahoo group so he seems to have disappeared. I like it because it has different algorithms and tweaks so you can see which gives the best results. It works with TIFs and you can take sequences of images to make AVI videos besides just stacking. It was written for Windows XP but I don't have any problems running it under Windows 7. I haven't tried it under Windows 10.

Update: Looks like the author is still active and has a newer version call czimps for Windows 7 and 10 - 64 bit only. Link do download at bottom of page. He has a link for CombineZP download there also. The author warns CZimp isn't not easy to use. CombineZP isn't too bad but not the most user friendly either.
