Hi Lavinia,
AdobeSerialization file require admin privileges to license the applications. Please make sure you run the AdobeSerialization file with admin permission. in case, apps still ask for Adobe ID, delete the SLstore from locations below and run the license file again.
WIN: C:\ProgramData\Adobe\SLStore
MAC: HD>library>application support>adobe>SLstore
Hope this helps.
Thanks,
Ashish
