# Where Do I Find the Lasernet Logs?

By default, 5 x 10 MB of logs are retained. The service instance `<InstanceName>` is the Lasernet instance name. From Lasernet Core 11, these are referred to as environments.

The default locations for Lasernet instance log files are:

- Lasernet 6.7: `%ProgramData%\Formpipe Software\LaserNet v6.7\<InstanceName>\LaserNet.lnlog`
- Lasernet 7: `%ProgramData%\Formpipe Software\LaserNet 7\<InstanceName>\LaserNet.lnlog`
- Lasernet 8: `%ProgramData%\Formpipe Software\LaserNet 8\<InstanceName>\LaserNet.lnlog`
- Lasernet 9: `%ProgramData%\Formpipe Software\LaserNet 9\Service\<InstanceName>\LaserNet.lnlog`
- Lasernet Core 10: `%ProgramData%\Formpipe Software\Lasernet 10\Service\<InstanceName>\Lasernet.lnlog`
- Lasernet Core 11.0: `%ProgramData%\Formpipe Software\Lasernet 11\Service\<Lasernet Core environment name>\Lasernet.<host name>.lnlog`. Appropriately substitute `<Lasernet Core environment name>` and `<host name>`.
- Lasernet Core 11.1 and later: `%ProgramData%\Lasernet\Lasernet 11\Service\<Lasernet Core environment name>\Lasernet.<host name>.lnlog`. Appropriately substitute `<Lasernet Core environment name>` and `<host name>`.

To change the log file location, follow the steps for your version of Lasernet.
