HI,

Are you running on 32-bit Windows or 64-bit Windows? Are you running on Windows 11, 10 or the obsolete Windows 7?

Thanks,

Andy

It’s windows 11 with 64bit

Strange - this error usually appears on Windows 7 machines. Is this Windows Server?

Try this fix:

  • Open Explorer and navigate to the LINKPlanner installation directory (the default is C:\Program Files\Cambium Networks\LINKPlanner)
  • Delete MPR.dll and MSWSOCK.dll
    • Note that you will need administrator privileges on the computer to do this

Also - try installing LINKPlanner as an administrator if possible.
