Some users may encounter the error Error 1923: Verify that you have sufficient privileges to install system services and/or Error 1939 when they attempt to update or install the Killer Control Center. This issue is caused by the installer not being able to remove the previous version of the service. This problem appears to be due to the moving of files by the Spring 2018 Windows Features Update. There were also some updates incorrectly pushed through Windows Update that has resulted in the Killer Control Center being in this state. To resolve this issue, you will need to uninstall the old version of the Killer Control Center, remove the service, and then rerun the installer. We have developed a new tool, which will quickly and easily remove all old versions of our performance suite, as well as all old versions of our service from your system. With this tool, you can clean install the latest Killer Control Center, resolving these issues.
A few notes about the Killer Software Uninstaller Tool:
- This application is not the Killer Remover tool that you might find elsewhere on the web and in this knowledge base – it is a brand new tool that we have just recently developed due to this issue. The old Killer Remover tool is not capable of resolving this issue, as it only targets pieces of installs that were broken by Windows Feature Updates before the 2017 Fall Creator’s Update.
- This tool does not remove device drivers, other than what the uninstaller usually removes for the suite that you have currently installed. This tool primarily removes the Killer Performance Suite and its attachments to Windows Update.
