If you happen to be running a 32-bit version of Windows, you won't need to do much to get it running natively. Unfortunately, the vast majority of users are running 64-bit versions of windows which means you'll need to emulate an environment that Outpost can run it.
We used to offer it as a downloadable package but since Activision published Outpost 2 on GoG, we had to disable the downloads of both games.
That stated, since you have the CD, that'll make things a bit easier. You'll need to download DOSBox and a Windows 3.11 ISO file (I don't know how far I can go in terms of pushing links but suffice it to say a google search will yield good results for safe downloads of Windows 3.11).
You'll also need to get S3 SuperVGA graphics drivers for Windows 3.x. This is a reasonably good guide for setting up DOSBox and Windows 3.x (

After you've got Windows 3.x booting in DOSBox, you'll need to map your CD drive in DOSBox. You can then go through and run the setup program within Windows.
DOSBox can be a bit daunting to work with so I'd recommend a front-end. I personally like
D-Fend Reloaded but you can find a bunch of other front ends here:

If you look at the DOSBox config file, look for

Hoping all of this helps.
