oops, i missed that part about a probable eduction version
your serial number must match the installation file. ie, platform, language, license type must all match:
so, if your license type is education, you need an education installation file.
there are no public links for anything other than individual licenses. however, if you registered with adobe (and you remember the adobe id used when you registered), you may be able to find a link in your account, account.adobe.com
