ServiceUI.exe error

Hi!

I'm using the ServiceUI.exe from MDT 2013 to open cmtrace.exe with "x:\windows\temp\smstslog\smsts.log".

The command line is:

ServiceUI.exe -process:tsprogressui.exe cmtrace.exe "x:\windows\temp\smstslog\smsts.log"

I get error code 0xFFFFFFFF and in SMSTS.LOG:

If I run the command in an CMD.EXE (F8 in Windows PE) I got the same error.
