Unable to uninstall MLNX_WinOF2 1.45

I´m unable to uninstall MLNX_WinOF2 1.45. After running uninstall in Windows “Add or remove programs” it reapperas after a few seconds.

What do I have to do to uninstall it?

Hi Christoph,

To uninstall MLNX_WinOF2 you need to have elevated administrator privileges.

You can uninstall it in one of the following ways:

  1. Click Start-> Control Panel-> Programs and Features-> MLNX_WinOF2 → Uninstall.

  2. Open a CMD console-> Click Start-> Task Manager-> File-> Run new task-> and enter CMD.


MLNX_WinOF2-2_0_<revision_version>_All_x64.exe /S /x /v"/qn"



I´ve tried both ways with elevated administrator privileges and it didn´t work. It still reappears in Programs and Features after a few seconds.

In the MLNX_WinOF2.log I get this error:

CheckIfPckgInstalled: ERROR !!! ,Mellanox WinOF package for is not installed
