Installation

 

Issue Title Description Potential Solution
GTT Launch User trying to launch GTT from a different account (which was not used for installing GTT). Please note this is not a valid scenario as this not fully tested , hence we recommend to use same account, which was used for installing GTT, to launch GTT.
SQL Installation Fails Installer complains that SQL RTM installation has failed.

 There seems to be another version of SQL Compact edition installed on the box.

  1. Cancel the installation  by clicking “No” or click OK.
  2. Restart the machine.
  3. Try the installer setup again.

Microsoft SQL RTM has a rule to check if there is any restart pending on machine, if pending SQL installation will fail.
Service Installation error message During installation below error message appears.

 This error comes if default .Net 3.5 is not enabled on windows.
Please check if the feature is enabled from windows features , to do this follow below steps:

  1. Goto Control Panel->Programs and Features.
  2. On left panel select View Windows features on or off.
  3. check if the below highlighted feature of .net is enabled or not.

  2. Run services.msc and check if Harman Audio Library service is in the list.
  3. If it is in the list:
  4. Run cmd (as administrator) and type sc delete “Harman Audio Library”.

Same steps can be used for Harman License Manager as well.
Database Error Message During installation at database selection step I am getting below error:
  1. Before installing GTT navigate to this location
    C:\Program Files\Microsoft SQL Server\MSSQL12.SQLEXPRESS\MSSQL\DATA
  2. Check if these two files are already present.
    • GTTData.mdf
    • GTTData_log.ldf
  1. If it they are present, take a backup of these files and delete from this location.
  2. Try the installation again.

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

To reach the above option,  Goto Control Panel > Clock and Region > Region > Administrative tab.
O Release Installation error During installation of O release I am getting below error
  • Before Installing , Goto C:\ProgramData\Harman\GTT folder.
  • Check if AudioLibraries folder exist, if exists delete or rename it.
  • Try installation again.
Installation failing without any specific error. In some scenarios we have seen, installation fails without any error, just says “Installation interrupted” This issue mainly come due to issue in SQL state on system. For example, if SQL port is blocked or service is in stopped state.

To resolve this follow below steps to write to database:

  1. Enable TCP\IP protocol and Named Pipes from SQL configuration manager.
  2. Restart 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 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 settings as shown in screenshot.

Make sure to do for both Client and server.

  • Restart SQLEXPRESS service.
  • Then try GTT installation.

Sometimes we have to repeat these steps couple of times so that GTT installer can write to database.
HarmanAudioworX installation fails with the following error snap shot.

 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 detects the installation and skips. Manually install the Microsoft SQL 2019 sever Express edition.

AmpSRV2

 

Issue Title Description Potential Solution
AmpSrv2 disconnected from GTT Disconnection can have several sources:

  • GTT request disconnect
  • Disconnect is requested by AmpSrv2 GUI / pressing ESC: Then you should get a message box like:
AmpSrv2 Disconnection
  • The socket connection between GTT and AmpSrv2 breaks, maybe cause by huge CPU load
  • AmpSrv2 detects an issue with RS232 interface. Are you using USB to serial converter? Did you checked with a different converter?
 Check whether GTT requests the disconnection by doing the following:

  • Start attached application in parallel to your test automation.
  • Choose corresponding interface inside of the tool and connect to AmpSrv2.
AmpSrv2 Troubleshooting

If GTT disconnects, AmpSrv2 should still be connected to the target device.

GTT GUI Issues

 

Issue Title Description Potential Solution
GTT Crashes while launching streaming window. Performance counters cannot be accessed while starting streaming. One of the reason, GTT may crash while starting streaming could be the Performance Counters are not properly initialized or they are corrupted. This could be solved by rebuilding the performance counters.

To rebuild all Performance counters including extensible and third-party counters, type the following commands at an Administrative command prompt. Press ENTER after each command.

Rebuilding the counters:
cd c:\windows\system32
lodctr /R
cd c:\windows\sysWOW64

Workaround for LUT parameter sets unit problem[Backward compatibility]

This issue will happen with every single LUT object in every set group with this device file. What seems to happen is the panel is appending the unit of each parameter into the set file, which is corrupting it.

This workaround required for projects which are exported earlier than N+1 release.

  • Import earlier exported project.
  • Open Signal Flow designer , if all LUT objects belong to same group, launch panel by double clicking any LUT object.
  • If  each LUT objects belongs to  different groups. Launch panels separately for each group.
  • Close opened LUT panels.
  • Open Parameter sets view , right click on column header of red color highlighted set and click ‘Store’  context menu to get latest set values.

You can observe red highlights are cleared and units are removed for each state variable.
Unable to import/export projects in GTT If the FIPS Algorithm Policy is enabled in the computer, GTT fails to import/export any project.

  2. Navigate to the Windows start bar and in the search field enter “secpol.msc”. This action opens the Local Security Policy editor.
  3. Under the Security Settings, navigate to Security Options, and locate the System cryptography setting.
    If the System cryptography setting is enabled, proceed to the next step to disable it.
  4. Double-click on the System Cryptography setting, choose Disabled, and then Apply.
  5. Reboot the computer.
  6. Launch the GTT and try to import/export any project.
