NSIS dism enable NetFx3 error 11 windows 2012

I want to enable .net3.5 in nsis installer in windows 2012. I used next code:

nsExec::ExecToStack 'cmd /c %windir%\system32\dism.exe /Online /Enable-Feature /FeatureName:NetFx3 /All'

But it return error 11.enter image description here

my dism log file: enter image description here

I run it on virtual machine, where I have only one user - administrator. If I run this command directly in cmd - everything ok.

Solution

It tells you what the problem is. It can't use the 32-bit version for whatever reason.

!include LogicLib.nsh
!include x64.nsh
