Uninstalling Onsite Managers

The purpose of this KB is to assist with the removal of an Onsite Manager cleanly from an end device and leave no trace of it behind. Partners might want to do that after they have migrated an OM to another device, or for a business sales pitch for the benefits of Managed Workplace as a RMM platform at a potential client site, or simply to remove it entirely for any other reason. In order to accomplish this, please follow the below steps.

To remotely uninstall an Onsite Manager

As of Managed Workplace 12.1, you can now remove an Onsite Manager from the site directly in Site Management. If you are doing this, it will remove all OM managed devices immediately without the ability to go in reverse. 

  • In your Service Center go to Site Management
  • Select Sites
  • Select the Checkbox beside the site in question
  • Click on More Actions
  • Select Remove Onsite Manager
  • Fill in the CAPTCHA and hit OK

Note: if the site has any Device Managers installed, those will be needed to be uninstalled with the correct knowledgebase steps.

To locally uninstall an Onsite Manager (using either A or B method)

A) Removing from Program and Features

  • Click on Start
  • Open Control Panel
  • Select Programs and Features (or Add or Remove Programs)
  • Select Managed Workplace Onsite Manager
  • Select Uninstall or Remove

B) Removing MSI Cache

  • Click on Start and open Windows Explorer
  • Browse to C:\Windows\Installer
  • Right-click on the Category bar beside Size and select More
  • Find Subject in the list and hit OK
  • Sort by Subject
  • Locate Managed Workplace Onsite Manager in the list
  • Right-click on the entry and select Uninstall

Note: If you are not reinstalling Onsite Manager, or installing an  Onsite Manager for a different site on the computer, you can eliminate any trace of the application by completing the procedures that follow.

To remove file system artifacts
  • Click on Start and open Windows Explorer
  • Locate and delete the following folders:

C:\Program Files\Level Platforms
C:\Program Files (x86)\Level Platforms

  • Click on Start and Run the command regedit.exe.
  • Locate and delete the Level Platforms key(s)


To remove database and artifacts
  • Open SQL Server Management Studio (SSMS) as Administrator
  • Connect to the LPIMWOMEXPRESS instance
  • In Object Explorer, expand Databases
  • Right-click MWData and choose Tasks
  • Select Detach
  • In the Detach Database window beside MWData select Drop
  • Click on Start and open Windows Explorer
  • Browse to C:\Program Files\Microsoft SQL Server\MSSQL13.LPIMWOMEXPRESS\MSSQL\DATA
    • Depending on version of SQL Server, this directory structure might vary slightly
  • Select the MWData.mdf and MWData_log.ldf and move or delete these
    • We recommend backing them up in case you want to restore so delete with caution in mind

Note: You can also uninstall the SQL Server if it is the only SQL Server on the device

To remove the service account
  • Launch Computer Management via Start - (Run) - type 'compmgmt.msc'.
  • Expand Local Users and Groups.
  • Right-click the account that was used to run MWExpertSystem (mwservice by default) and choose Delete.
  • Click Yes to confirm.

If your intention is to re-purpose the device as an Onsite Manager at a new site, the system should now be clean and ready for use.
