As you can see this has Creatures 3, it's patch, Docking Station, and all the Creature Packs in one nifty package
for your convenience.  There are however a few notes I would like to include to prevent any troubles from the
ones I came across and it is mostly from experiences I've had in running the game on something that is not 95, or 98.

Basic steps:
1) Mount the Creatures3.iso image using Daemon Tools or a similar program. (Located in the Creatures + Patch dir)
2) Install Creatures 3
3) Apply Creatures patch 2 (found in same place)
4) Install Creatures packs* (Found in Creatures Pack directory)
5) Install Docking Station*  (Found in Docking Station directory)
* Steps 4 and 5 can be done in either order.

Notes about Win 7, Vista.
--
The game DOES run fine in Win 7 since I am currently running this on my lappy.  The only thing you have to do is switch to 16 bit mode when playing with the Docking Station, this is the same process for Vista.   Also for 7 and Vista, don't install DX-7 or try to... it will tell you it does not support it and the install will stop, so just hit no and ignore the warning... IT WILL STILL WORK!    For Vista you MIGHT need to enable a compatability mode.. but I'm not 100% sure on that one.  I was testing it on my friends laptop and I had it running on there as another guide said, mostly because her computer is in need of a format, more ram or both and it runs badly. 
I've also read and seen that some people running 64bit Win 7 seem to be having problems running the game, while others do not.  As it is, those who have had problems have reported at least that they where able
to run the game through VirtualXP and do so decently.  Really before you try that though, I'd say just try and see what happens.
