We ask you to confirm your choice during purchase. You can certainly upgrade to a higher version, given that all the modules in the STANDARD edition are also part of the ELITE edition.
On the other hand, you cannot “downgrade” from the ELITE edition to the STANDARD edition if you've already activated your software.
To bring your version up to date, go to your customer account by following this link:
