There is no "academic" *edition* of Windows XP. There is, however, an
academic scheme for pricing and a restricted audience. Academic means
you must be either a teacher or student using the product. It is likely
to be a retail copy but marked down in price since it is a promotion
that is available only for academia. Academic refers to the license and
the restrictions to who can use it and under what conditions. Are you a
teacher? Are you [still] a student? Do you have a *full* license of a
prior version of Windows against which you can apply the *upgrade*
academic license?

Since you never identified HOW you acquired the product, no one here
knows what were the conditions between the reseller (school) and you, or
the terms between the school and Microsoft for what type of license they
acquired. Go back to whomever sold you the academic *license* to find
out what are its conditions.
