wyUpdate.exe and /noerr

Hi,

We use the method to silently check for update by using wyUpdate.exe -quickcheck -justcheck -noerr.

If we don't use the -noerr argument, wyUpdate shows a dialog with an error if there's one.

Is there a way to retreive the error with the -noerr argument that would be displayed without it? Because we want to display our own message and log the real error in a file for support purpose.

thanks
