Is there any?  I can't seem to find any kind of install document.  We are lookting to seriously purchase this product, but if I can't find any documentation.. I am going to have some serious reservations.

Here are some questions I am looking to get answered:

Is this installing Apache (it appears so but I would like to confirm)?

Can it use IIS instead?

If not then do we know of know issues installing apache and IIS sidebyside?  I have to put this on a server that already has several website.  I can make sure they don't use the same port, but did they make sure apache doesn't try to claim port 80?

Thanks.
