DISM Error Code 11 while running 64bit CMD via 32bit SCCM client.

I needed to run deployment image servicing and management tool ( dism.exe ) in an SCCM installation program, and I needed to call that via cmd.exe. I was getting Error Code 11 : You cannot service a running 64bit OS with a 32bit version of DISM. Please use the version of DISM that corresponds to your computer's architecture. The DISM log file can be found at C:\Windows\Logs\DISM\dism.log

 

 

The cmd.exe under system32 is 64bit but running c:\windows\system32\cmd.exe /c …. still causes problem if it’s called from 32bit app, like sccm client or c:\windows\syswow64\cmd.exe

So calling c:\windows\system32\cmd.exe explicitly didn't help.

The solution is using sysnativealias, example : c:\windows\sysnative\cmd.exe

Because when you use sysnative you also say don’t redirect me to windows.

You may experiencing this problem for DISM operations in Windows, in that case change your working folder to C:\Windows\System32 or call DISM from this folder to get rid of this error.
