|You have just contradicted yourself. First you asked the question If there is NO NET.Framework at all in WinXP, what downloads will satisfy Paint.NET's needs? (How many downloads) Then you say I DO KNOW, having tried it, that Paint.NET will NOT install without any NETFramework.|
Why bother asking the question in the first place? Vote all you want - Your response does not matter nor do I care.
By the way Paint.net system requirement cited on this page cited that you need .Net Framework 3.5 SP1.
As for the Net Framework architecture I mentioned, read about it HERE.
