Hi Mark,
Yes, I am having the same problem as OP. I downloaded the 30-day trial version of Autocad LT 2018 last month. The download went fine. After the 30-day trial, I decided to purchase a 1-year subscription to Autocad LT 2018. I reinstalled Autocad LT 2018. Now, every time I try to start up the program, I am getting the license manager is not functioning. I have completed an uninstall and reinstall of Autocad LT 2018 5 times. I still can not get the program to start. I am running under Windows 10.
I am not sure what to do next.

Technically you don;t have the same problem as the original poster..   Their issue is related to a renew subscription message that leads to a license manager is not functioning message.   You have a separate type of issue that leads to the license manager not functioning and thus requires different steps.  That's why I asked...

Perform a license reset by following these steps:

Please note, folders of C:\Programdata and C:\Users\[Username]\Appdata (listed below) are hidden folders and you may need to adjust your viewing settings.

First make sure you're signed out of the desktop app and A360 (both are located in your Windows system tray

On your computer, navigate to

2017 Version: ​​C:\ProgramData\Autodesk\CLM\LGS\<Product_Key>_2017.0.0.F  [<Product Key> is the product key of the application you have]

2018 Version: ​​C:\ProgramData\Autodesk\CLM\LGS\<Product_Key>_2018.0.0.F  [<Product Key> is the product key of the application you have]

Delete the LGS.data file.
Navigate to C:\Users\[username]\AppData\Roaming\Autodesk\ folder
Delete the ADUT folder and it's contents

When you start the application, it will prompt you to choose one (that matches your license) of the following:

Login - 30 day trial or CLIC (Cloud Based) licenses
Serial Number - Students, Standalone and Single-User Term Based activation
Network - Network License server for obtaining licenses from a machine on your network

Good luck and report back on your progress

Hi Mark,

Thank you very much for your help. It turns out that I was not doing a complete (or clean) uninstall. I followed the “Perform a Clean Uninstall” instructions from the AUTODESK KNOWLEDGE NETWORK. I then reinstalled Autocad Lt 2018 and now everything is working. The “Clean Uninstall” procedures did include the steps you outlined.
Again, thank you for your help,
Fred

Thanks for the reply. I think I have same problem as ftennyso too. Now I'm using 30-day trial version but I already subscribe 1-year AutoCAD LT 2018. I have tried clean uninstall several times but it doesn't working. Maybe I have miss some steps ? Or I cannot use the installation file that free download from trial version website?

Thank you.

There is a very important Hotfix that Autodesk recently issued. I must have had my auto install updates turned off in the Autodesk App because I missed it. I, too, used the 30 day trial, leased a 1-year seat, and when through all of license manager issues that everyone listed. I did a clean uninstall and reinstall at least six times and followed followed advice listed on the forum without any success. I worked with one Support Team member who remotely accessed my computer and ran through all of the possible troubleshooting steps that he could think of without success. My case was transferred to a more experience team member who installed the Hotfix, did a clean uninstall, and reinstall and it FINALLY worked. After losing AutoCAD for over a week, I am totally elated!
