I don't know if it is the right part of the forum for this question but I didn't find a better match.

My personal account is associated to a commercial licence when I launch the maintenance tool, but I want to have an open source licence to avoid the problems of licence checking errors during compilation (The version that I have at home is just for personal dev, I have an other commercial version in my company and the two licences have different email address).
Do you know how to change from commercial to open source licence for my personal account ?

Thanks !
