Error 1721 Upon Killer Network Manager Installation

Please note that this KB article only pertains to legacy products. If you are encountering issues with a currently supported Killer Network Adapter (Killer E2200, E2400, E2500, and all Wireless adapters), we suggest clean installing the Killer Control Center to replace the Killer Network Manager, as the Killer Network Manager is no longer updated.

Click here for our guide on clean installing the latest Killer Control Center. 

PROBLEM: Upon installation of the 6.0 software suite, you receive this error:

*Bigfoot Networks Killer Network Manager Error

*Error 1721. There is a problem with this Windows Installer package. A program required for this install to complete could not be run. Contact your support personnel or package vendor. Action: RegisterLSP64, location: C:Program Files\Bigfoot Networks\Killer Network Manager\KillerTool.exe, command: -lsp-map

SOLUTION: Install Microsoft .NET Framework 3.5 Service Pack 1. This update is also part of the Windows Automatic Update.

You can find the direct download here.
