Dllhost.exe sandboxed as blocked

I was running CD in sandbox mode, i checked the logs and saw this. Should I be worried? Did CD run this?

Is dllhost.exe in the system32 folder? Then is most likely a legitimate Windows file: dllhost.exe Windows process - What is it? .

Do you recall what the parent of dllhost.exe was? If the parent runs sandboxed and it calls dllhost.exe it will be sandboxed too.
