Updated Civil 3D 2023 with the most recent update and License Services now I have an error message and can't work

Any help appreciated, I'm locked out of Civil 3D 2023 and also Vault 2023. 

I called our IT service today to have my products updated (we don't have admin privileges).

First we installed Autodesk Licensing Service - 14.0.0.10160 - Win - Update for Civil 3D 2023 then installed Civil 3D 2023.3.1 Update and now I get this error message:

What did we do wrong?

I fear we have to uninstall and reinstall everything. The IT guy tried reinstalling Autodesk Licensing Service but now nothing happens when we double click on it...

We also tried to installed Civil 3D Grading Optimization to see what would happen, and we can't go on with the installation, we get the error 1603. We emptied the Temp folder and also the Windows's temp folder (which I can't remember the name).

Problem solved.
We did a roll back of Windows but we still had the problem. What we found out is we only had to follow the procedure here: https://www.autodesk.com/support/technical/article/caas/sfdcarticles/sfdcarticles/How-to-uninstall-A...

Sometimes, IT are so used to do things their way. We couldn't find Autodesk Licensing Service in Programs and features (Control Panel → Program and features), you have to uninstall the ALSP from the uninstall.exe in the folder. So we did, then I reinstalled the previous ALSP I still had in my Download folder, so I installed it and everything was back to normal.

I uninstalled & reinstalled 2024LT but still seem to be stuck on licensing error? Checked for other updates, I already had the recent downloaded. Tried restarting a few times.. it's been a morning. I'm about to give up on it and go back to an older version.

Have you tried uninstalling the License Service?
