Trend link 6.0 license issue

Good evening and welcome to the community!

I see that you tried to use your existing serial number to pull an additional Trend Link license.  The serial number you used does not have any additional Trend Link license available.  I believe this is why you are seeing the error message you posted.  

Trend Link has been replaced by the dashboarding and trending tool Axiom.  We have been using Axiom since Canary version 10 (current release is 21.4).  I would recommend we upgrade your current Trend Link licenses with Axiom as Canary no longer sells or supports Trend Link. 

Our normal upgrade cost is $500 per license.  Additional Axiom licenses can be purchased for $995.  Each license allows a single concurrent user but multiple clients can share a license as long as they are not logging on simultaneously.
