It can happen that your request ends up in the spam filter. Some general tips:
1. Avoid using a generic email address like gmail, hotmail, yahoo,.... .
2. Have an email signature so they know who you are. They need to be able to identify your account.
3. Avoid adding attachments for this specific contact address (spam filter!!)
4. Add your server MAC address AND the version number of the target Innovator!
5. Maybe add a short description why you need the license (server update).
It still should be possible to get licenses for legacy versions. Aras has just removed the license generator from the homepage for a few practical reasons.
1. It helps them to identify which Innovator instances are alive and active.
2. Prevents people from registering dozens of instances that are never used
3. Prevents people from registering dozens of instances that ARE used (=ensures a fair usage of the open release).
4. Bonus: It offers their sales team a reason to reach out to you :)
Nothing to worry about. Last year, Aras experimented a bit with the open release formula. It’s still an ongoing process.
