License Errors When Starting Autodesk Software

When your Autodesk product works as expected, life is good.

Suddenly, you start getting license errors when starting your Autodesk software. So, you do extensive googling and find what you are sure the problem is, and you try the suggested fix(es). But, when you start your software you get the same error, AGAIN!

It appears to you that the hotfix and/or update installed, because it is no longer in your Autodesk Desktop App, but when you still get the error and your software won’t start, what are you to do?

Without knowing the exact cause, I believe that, in part, the problem is a failed install of the update or hot fix . . . and if you try to run it again, you will receive a message that the update is not necessary or already installed.

We have had consistent success fixing this problem by first removing the license components and then installing the current versions. I hope the following steps work for you, too.

Removing the Autodesk License Components

1. If the user is logged into the Autodesk Desktop App – log them out.
2. Open the Task Manager and end the AdSSO task (it might restart and may need to be stopped a second time).

3. Open Control Panel > Programs & Features > select the Single Sign On Component > choose to Uninstall it.

4. Navigate to C:Program Files (x86)Common FilesAutodesk SharedAdskLicensing and run uninstall.exe. If there is anything left in the folder after the uninstall, remove it.
5. Navigate to C:Users<user>AppDataLocalAutodeskWeb Services and remove the following files:

a. Event.xml

b. EventTrigger.tmp

c. LoginState.xml

Installing the Autodesk License Components

6. Sign into the user’s Autodesk Account and download the following updates:

7. Run the two updates:

a. Autodesk Licensing Service – 11.1.1.17 – Win – Update

b. Single Sign On Component 2020-21 11.3.0 English-US Update (AdSSO.msi)

8. Restart the computer.

9. Start your Autodesk product.
