During installation at the database selection step, getting below error.

Solution

1. Before installing GTT, navigate to this location
   C:\Program Files\Microsoft SQL Server\MSSQL15.SQLEXPRESS\MSSQL\DATA
   
2. Check if these two files are already present.
   – GTTData.mdf
   – GTTData_log.ldf
3. If they exist, create a backup of them and remove them from this location.
4. Then, attempt the installation again.

There are chance that the below checkbox is checked. Uncheck this.  This is available in Control Panel -Time & Language > Region Settings.

To reach the above option, go to Control Panel > Clock and Region > Region > Administrative tab.

In some scenarios we have seen, installation fails without any error, just says “Installation interrupted.”

Solution

This issue mainly comes due to an issue in SQL state on the system. For example, if the SQL port is blocked or the service is in the stopped state.

To resolve this, follow the steps below to write to the database:

1. Enable TCP\IP protocol and Named Pipes from the SQL configuration manager.
2. Restart the SQLEXPRESS service from SQL Configuration Manager.
3. Enable TLS 1.0 protocol, to do this in RUN-> type regedit, press enter.
4. Navigate to the key in the registry.
   (HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\
   SCHANNEL\Protocols\TLS 1.0)
5. Under TLS 1.0 u will find Client and Server, for both the keys, do the settings as shown in the screenshot.
   

Make sure to do for both the Client and the server.

• Restart the SQLEXPRESS service.
• Then try the GTT installation.

Sometimes we have to repeat these steps a couple of times so that the GTT installer can write to the database.

During installation getting below error.

Solution

• Before Installing, Go to C:\ProgramData\Harman\GTT folder.
• Check if AudioLibraries folder exist, if exists delete or rename it.
• Try installation again.

Sometimes the SQL Express is not installed with the pre-reqs. This may be because the system would have had the SQL Express installed previously and uninstalled, however, the registry is not cleaned properly, and the Pre-reqs wrongly detect the installation and skip.

Solution

Manually install the Microsoft SQL 2019 server Express edition.

Link: SQL_2019

If the machine has been upgraded from Windows 10 to Windows 11, the AudioworX_PreReq installation fails due to SQL Server Express 2019 incompatibility.

Solution

If the machine has been upgraded from Windows 10 to Windows 11, ensure the following registry key exists before proceeding with the SQL Server Express 2019 installation.

To add the registry key, open Command Prompt as Administrator and run the following command:
REG ADD “HKLM\SYSTEM\CurrentControlSet\Services\stornvme\Parameters\Device” /v “ForcedPhysicalSectorSizeInBytes” /t   REG_MULTI_SZ /d “* 4095” /f

Once you have added the registry key, run Setup_HarmanAudioworX_PreReq_2.2.0.2450.exe.

When you are trying to launch GTT from a different account (which was not used for installing GTT).

Solution

This is not a valid scenario as it has not been fully tested. Hence, we recommend using the same account that was used for installing GTT to launch GTT.
