Revit Licensing Error 2

[jporter]

I have a user who is experiencing a Revit Licensing Error 2 error upon launching Revit 2018.  Everything was working fine yesterday, but for no apparent reason it all stopper working today.  His Revit 2019 launches fine, just not his 2018. 

I saw these posts on the forum but with no true resolution:

Has anyone else experienced this, and, if so, have you found a resolution?

This is what was done to resolve the solution for this instance (can't promise it will work for everyone. . .you'll understand why in a sec):

1. Installed the latest Windows updates (Checked Revit and it still didn't work).
2. Rebooted the system.
3. Installed any and all Revit and Navisworks updates (since Navisworks was on the system as well).
4. Launched Navisworks Manage and selected the serial number (NOT THE SIGN IN) option.  It asked for a serial number, but instead ran it in trial mode. 
5. Launched Revit and it opened with the user credentials already signed in. . .not sure why.
6. Uninstalled Naviswork Manage 2018 using the Autodesk uninstall tool.
7. Rebooted the system. 
8. Installed Navisworks Manage 2018.
9. Launched Navisworks Manage 2018 and selected the sign in option and it opened with no issues.  

So now both Revit 2018 and Navisworks 2018 are both running.  

Again, now sure why this worked, but I'm not going to "look a gift horse in the mouth".

I struggled with the same problem and your (also Autodesk) solution has not helped.

What solved my problem:

I pushed one product with worked with sign on and noticed that aplication is doing LGS.data with only _USER value.
So i populated that LGS.data (only _USER inside) to other folder/folders for the version, with I had a problem to open.
example: for Revit 2018 folder name \829J1_2018.0.0.F

make your own check those websites:

I forgot to add paths for example:

C:\ProgramData\Autodesk\CLM\LGS

I had a very similar scenario. Revit 2017, 2019, 2020 worked as intended. However the one product I needed to use which was 2018 produced Licensing Error 2.
After following all of the recommended instructions, none proved to resolve the issue.

This is what resolved the issue for me.

I had to rename this folder:

"C:\Users\<USERNAME>\AppData\Local\Autodesk" 

to

"C:\Users\<USERNAME>\AppData\Local\Autodesk.OLD"

Then launch Revit 2018.
I was prompted to sign into Revit with my Autodesk ID and Autodesk Password.

I also noticed that what simply helps:

1. Logout at Autodesk Desktop App (do not log in again).

2. Start not working 2018 product and software will automatically ask you to log in.

Hello,
I have solved this issue easily.

1. Turn off all Revit instances
2. Open the Autodesk Desktop App and sign out
3. Start Revit 2018, the login window will pop up
4. Sign in with your credentials 

I've had some licensing problems before and this helped there too.

Good luck!

Yes Adam you are totally right.

I was also using that solution but forgot to post it here.

But thank you bye the way!

One other thing that may be related is that Autodesk has been busy pushing updates for the Autodesk Desktop App over the last 2 months (I think 3 so far). What I've noticed is that users in our firm have received licensing errors as a result of the updates. The earlier ones don't automatically install and require the user to open the app and click OK to allow the update to install.

In order to get past the problem we have had to get the users to open the Autodesk Desktop App, allow it to update, and reboot their computer. Note the app update doesn't tell you to reboot, but trust me it is needed. The other thing that was critical is opening the Settings panel in the app and enabling 'Allow app to automatically update'.  This in combination with some of the other suggestions has fixed the problem for us.

This works a charm and is by far the quickest solution, thank you.

This helped solve several of my issues. Certainly inconvenient, but allows you to continue work so you do what you have to do.

Would be nice if Autodesk would address this and at least allow us the option to sign in separately after opening on these older products that are being "phased out".

I found this was caused by the licensing service and the Autodesk Desktop App.

Resolved by carrying out the following:

1.  Updated licence service via desktop app. (at time this was 12.0.1.5 - Win - Update).

2.  Signed out of Desktop app and desktop connector.

3.  Signed into Revit no problem with LGS data file set to "_USER".

4.  Restarted laptop to allow Autodesk Desktop App to log in correctly.
