aswClear utility command line for Avast! 5 Free

I’m trying to find out is the aswClear.exe utility will still work from the CLI with Avast!5 and the free version (which launching the utility is reports in the same section as the pro edition).
I’ve tried several of the documented command posted but they don’t appear to work.

Thanks,
Sam

Are you using the latest version of aswclear? Are you running it under Windows Safe Mode? http://www.avast.com/uninstall-utility
