Change License Server Inventor 2021

[Ed__Jobe]

I installed Inventor 2021 as a trial. Now that I updated the license server, I tried to activate the software, but I think I misspelled the server name or got the wrong syntax because Inventor says there are no licenses available. How can I change the name of the server? Each time I try to activate it, it just says there are no licenses. I found some posts on the subject but they were for AutoCAD.

can you open up inventor?

if so try this see screenshots

Thanks Darren, I tried that already, and I get this screen.

Each time I choose "Use a network license", it just pops an error dialog. I don't get the chance to specify the server.

try adding this enviroment variable: https://knowledge.autodesk.com/support/autocad/learn-explore/caas/sfdcarticles/sfdcarticles/How-to-s...

I added it but it didn't help. I found the lic file and renamed it, but when I restarted Inv, it recreated the lic file with the wrong path. I searched the registry but it didn't find any key with the wrong path. I also verified lmtools that the server has the licenses installed. The main problem still is that I can't change the license type in the software.

I did another test on my laptop. I installed IV and used the correct path to the server and I get the same error message. How can I find out if the license is working properly?

[DarrenP]

run a status enquiry on the license manager

[Ed__Jobe]

It lists them, so I don't know why it's not working. Initially I use the server's fqdn, but I see in AutoCAD it's just using the server name "licensing", no port number. On my laptop I followed Adesk's directions and used "27000@licensing" as it shows in lmtools, but it could be that name is wrong too. I know it works in AutoCAD without the port number, but unfortunately, I can't change it on my laptop either. Stuck...

[DarrenP]

can you post a screenshot of the error message?

[Ed__Jobe]

Sure.

Is there any client that can get a license from the server? If no, there might be a firewall issue. Ports 2080 and 27000-27009 needs to be open

Try these strings in an Internet browser from the client:

http://<yourlicenseserver>:2080 and  http://<yourlicenseserver>:27000

Both should give a string in response:

Wê-60Wê-60Wê-60Wê-60Wê-60

Use Internet Explorer, it returns this, but Chrome & Edge gives ERR_INVALID_HTTP_RESPONSE

Firefox gives this response:

Wê-60�����������������������������������������������������������������������������������Wê-60�����������������������������������������������������������������������������������Wê-60�����������������������������������������������������������������������������������Wê-60�����������������������������������������������������������������������������������

If the response isn't like one of the above this the ports need to be opened in the license server.

thanks for replying, but that's not the problem. As I mentioned, other 2018 apps work, just not IV 2021. I can get server info from lmtools on my pc.

[GunnarNilsson]

Ok, what version of lmgrd.exe and and adskflex.exe do you have? For 2021 licenses you need 11.16.2.0

[Ed__Jobe]

Yes, that's what Darren suggested. I've asked IT to check on it. Thanks.

[Ed__Jobe]

The server still had the 2018 license manager. Its working now. Thanks all.
