Where to install zip content? about umqttbroker HOT 4 OPEN

Thanks Martin for your quick reply.
I did install it right the first time then! However I can compile uMQTTBrokerSample.ino fine if I set the
IwIP variant to "V2 Higher bandwidth" with no errors, I get all sorts of errors if I change it to "V1.4 Higher Bandwidth" as suggested in your readme.md as a small portion of it shows bellow.
This is why I thought maybe I had installed it wrong. But since it compiles fine under V2, I don't know where the problem is. Sorry for bothering you with my stupid problem.

Thank you for this report - the new Arduino ESP bord package v2.5.0 breaks this. I just uploaded a new version that should compile with the new version. Alternativley downgrade the ESP bord package to v2.4.2. This is known to work.

Since I was running v2.5.0B before, I must report that it too did not work and that's why I upgraded to v2.5.0.
I've re-download the new zip and it compiles clean now. Thanks again for your help.
