When you link a Lansweeper Classic installation to a Lansweeper Platform site, one of the prerequisite checks confirms that your Lansweeper license is eligible for linking.
Why this check runs
Not all Lansweeper licenses are eligible for linking. Eligibility depends on factors such as license type. Certain legacy licenses aren't eligible.
Resolve a failed check
Confirm you've applied your most recent Lansweeper license. If you applied a different license, try linking again.
If the check still fails or you're already using the correct license, contact the Sales team to discuss your licensing situation.
When all prerequisites pass, you can link your installation to a site.
