Floating Licenses
Floating Licenses can be shared between multiple users and can be used completely online or within a local network, depending on the setup.
To use an online floating pool, your Administrator needs to add you to their Organization. This sends an automatic email confirmation, which also contains a link you can use to create an account, if you don't have one yet.
After that, you can follow the same activation steps as above to connect to the online floating pool.
- Proceed with a default installation.
- Sign in with your Chaos Account when prompted.
If you are an Administrator in an Organization, see the Cloud-Based Floating Licensing page for a guide on how to share licenses through the my.chaos portal.
