Snow leopard and 3.2.6 xcode

Question

To begin Snow leopard is 10.6.8 up to date.
Well, as I only been searching up and down the web for a solution to this problem, I have found alot of dead ends and unanswered problems.
Xcode 3.2.6 Seems to be the must rare thing in the universe to come across, or at least for myself it is.
I'm running Snow leopard hint the title.
It came with a disc, oh wait isn't that a wonder since thats the only way you can download it, as I'm aware of, and almost absurd you can digitally download mavericks.
Anyways the xcode that comes with the optional install on the disc only is up to date to 3.0, isn't that shocking since i wasted my time and money getting snow leopard because of the many problems apple has with almost everything (leopard & openssl cert.) which was a pain in the *** to begin with.
Warning: Xcode is not installed
Most formulae need Xcode to build.
It can be installed from https://developer.apple.com/downloads/
As the above is pretty ******* obvious what the problem is, where the real problem lies is that i can't install it.
When i go to install: xcode_3.2.6_and_Ios_sdk_4.3.dmg everything appears to be fine until it actually starts to verify it and in less then about ten second everytime it is denied.
I've gone through **** trying to figure this out and even the programmers at my local business are unable to figure this problem out because there is absolutely no explanation to why it won't install. It does not give me a hint of any sort, it is simply put "verification unable to process"
Now before I thought of actually coming here and looking for help i have reinstalled xcode and snow leopard numerous times to recieve the same problem.
Quite frankly I do not wanna put more money into lion as I heard first off its a waste, and secondly why should I keep spending money and getting the same **** results.
I heard about getting Xcode 4.2 but I'm not even sure this is compatible with Snow leopard let alone the link is busted and access is denied due to having to be a paid member on the apple site, (which at this rate will never happen)
I don't mean to be rude, I'm just a twenty one year old kid with a bit of furious attitude who doesn't like to waste his time and money.
But please if this at all gets answered (which I'm almost positive it won't from everywhere else i searched no answers are being given) that it at least be related to the cause, as I can see alot of people are in the same situation and therefore i believe a REAL solution should not be left unheard.
If any more information is needed, please feel free to ask. I will be checking in so often to to hopefully come back to a fix.
Thank you for letting me waste your time.
