Hello,
This may happen if you don't have a
Floating license type. The license server can be used and configured only by registering it with a
Floating license.
If you have a
per-developer license, then you should use your license key to register the Advanced Installer application by using one of the first two option from our
registration wizard.
If you do have a Floating license, but you cannot register the License Server please send us an e-mail to
support at advancedinstaller dot com including your Floating license key and a detailed test case you are using to replicate the issue.
All the best,
Daniel
