any windows version 98, XP, Vista, Win7 will work. There is really no requirement (although I agree, never vista!). mySQL just has to install. I use ubuntu linux. Works great and never goes down.
I think that the documentation on the website should be updated to include more clear details on the supported version. http://www.opendental.com/manual/comput ... ments.html As it is right now that document is not exactly comprehensive or detailed. Were it a WIKI I would fix it myself.
