Hello
Trying out LanSweeper.
1 - Installed LanSweeper, localDb.
2 - Pasted Trial Key.
3 - Started LanSweeper and resctricted access to a AD group (yes, I'm member).
4 - Restarted the pc.
After restart - the localDb service will not start "Service cannot be started. The handle is invalid" ?
----
Next step:
A - Uninstalled LanSweeper and all it's components.
B - Restarted PC.
C - Install LanSweeper again.
Now LanSweeper cannot be installed, because .... the localDB service cannot start ?!?!?!?!
---
Questions
- What causes the localDB not to start in the first place ?
- What is not uninstalled / removed completely, when uninstalling LanSweeper ?

When you uninstall Lansweeper and were using the LocalDb database provider, SQL LocalDB 2014 will be left behind on your machine. This is because we cannot determine with absolute certainty that no other application was making use of SQL LocalDb, and we could otherwise inadvertently break another application.
Ordinarily, if the LansweeperLocalDbService was able to start during your initial installation, I would expect it to be able to start successfully in the future as well. During the start of this service, your SQL LocalDb instance is created, your Lansweeper database is created and the user you used to install the application with is given admin rights on the instance. It is possible to get a "handle is invalid" error if you renamed the computer, or if the user you installed the application with no longer exists or is corrupted (e.g. userprofile issues).
As an alternative, you could install Lansweeper using SQL Server. The free Express edition can be used:

- Configure your SQL Server instance to host your Lansweeper database (straightforward): https://www.lansweeper.com/knowledgebase/sqlserver-enable-mixed-authentication/
