Windows can't find 'slui.exe'. Windows Thin PC activation.


  • Hello,

    I am trying to activate windows ThinPC, after i click 'change product key' link to activate, this error pops up.

    'windows cannot find c:\windows\\system32\\slui.exe. make sure you typed the name correctly, and then try again. '

    I am using evaluation copy and have volume license key but evaluation media was downloaded from software assurance on

    I can't even go to the window to enter the product key.

    Why slui.exe file is missing and where can i get that file from?

    Please guide me,

  • Hi,

    The evaluation media is hard coded with a 90 day timebomb.  You cannot apply a Volume License key to the eval media.  SLUI.EXE is removed on purpose from this media.  Supplying a copy of the binary will not help.  You must obtain Volume License media through Software Assurance.
