Resolving “mySQL error” on Prescreen

The mySQL error occurs when a specific service of the Prescreen software does not start after running the software. The reason can be the software not starting correctly or an antivirus software deleting it all together. 

Step 1: Anywhere on your PC, press the [ctrl] + [alt] + [del] keys. Open “task manager” from the list of options.

Step 2: Open the Services tab, find the service in the image below and check if it is “stopped”. Right click on the service and click start. 

Step 3: If not present in the list of services, go to the following file location on the device to check if the service installed:

This PC > Local Disk (C:) > Users > [User] > AppData > Roaming > OneScreen Prescreen > mySQL > bin

Step 4: If the service and/or folder are not present, the antivirus software may have stopped the complete installation. Hence, the Prescreen software will need to be uninstalled and then reinstalled, while turning the antivirus software off during the entire process.

Steps to uninstall Prescreen from the device:

Step 1: Go to the following file location on the device on which PreScreen is installed:

This PC > Local Disk (C:) > Users > [User] > AppData > Roaming > OneScreen Prescreen

Step 2: Double-click to run the OneScreenPreScreen_stop file (highlighted below):

Step 3: Open the Control Panel on your PC.

Step 4: Under “Programs”, click on “uninstall a program”.

Step 5: Search for “OneScreen Prescreen” (highlighted below) in the list of programs and then click on uninstall/change (marked below).

Step 6: As a confirmation for complete uninstallation, go to the following file location and look for the OneScreen Prescreen folder: 

This PC > Local Disk (C:) > Users > [User] > AppData > Roaming

If the folder is absent, the uninstallation was successful.

However, if the OneScreen Prescreen folder is still present, the uninstallation might not have removed the software completely. To do so, follow the additional instructions below:

Step 1: Anywhere on your PC, press the [ctrl] + [alt] + [del] keys. Open “task manager” from the list of options.

Step 2: In the Task Manager, Open the details tab, find the processes in the image below and right click on each and select “End task”.

Note: Skip any that are not present/running.

Step 3: In the Task Manager, Open the services tab, find the processes in the image below and right click on each and select “End task”.

Step 4: After ending all the tasks, return to the Prescreen folder location and delete the folder.

Upon successful completion of all uninstallations, run the OneScreen Prescreen Set-up file on the on the device that you wish to run/use the Prescreen on. You can refer to our installation guide on how to do so.
