LabSolutions not starting - "[190b] Failed to start up the LabSolutions" - Red LSSService icon

Note: This article is relevant to all versions of LabSolutions (versions 1.xx, 5.xx and 6.xx). However, for DB/CS editions of LabSolutions (versions 1.xx and 6.xx), this error can also be caused by an error accessing the database. If the article below do not solve the issue for LabSolutions DB/CS, contact Shimadzu Informatics.

If the above error occurs when trying to open (a previously operational) LabSolutions, it is often due to a problem with the LSSService.exe background service.

The background service LSSService.exe is essential for normal operation of LabSolutions.

Under normal operation, the service monitor icon in the Windows Taskbar is green , if the service icon is yellow , this means that the LSSService is still starting up (this is normal for ~1min after booting of the PC).

If the icon remains yellow after ~2min, or turns red , there is a problem preventing the LSSService.exe from starting, follow the steps below:

Firstly, try rebooting the PC. If the problem persists, try to set the service to a 'Delayed Start' status. This can be done using the steps below (Windows Administrator access required):

• Open the Services app in Windows (type 'Services' in to the Windows search bar and click 'Run as administrator') 
• Find the LSSService in the list and right click on it, select 'Properties' (see below):

• In the 'Startup type:' pull down option, select 'Automatic (Delayed Start)' (see below):

• Reboot the PC, after ~2min, check to see if the service monitor icon turns green
• If the icon is now green, LabSolutions should open normally

If the service monitor icon still turns red , or remains yellow , this may be down to corrupted .mdb files (perhaps caused by unexpected OC shutdown/power outage). Follow the steps below to try and address this issue:

• Make backups of the files below and store them in a folder somewhere different to their current location:

C:\LabSolutions\Log\LSSLocalLog.mdb

C:\LabSolutions\System\LoginManagement.mdb

C:\LabSolutions\System\LSSProfile.mdb

C:\LabSolutions\System\LSSProfileObstacle.mdb

C:\LabSolutions\System\ShimadzuAttest.mdb

C:\LabSolutions\System\ShimadzuAttestObstacle.mdb

• Now delete the original files and reboot the PC.
• When the PC has rebooted, it should automatically create new versions of the deleted files.
• If successful, the service monitor icon should turn green and LabSolutions should now open normally.

If the service monitor icon remains red after these steps, a complete removal/re-installation of LabSolutions by an engineer is possibly required. If the LabSolutions version is DB/CS (1.xx, 6.xx), contact Shimadzu Informatics, as problems accessing the database may also cause this issue.
