Deployment cancelled and now the remote install service cannot be deleted

[ame]

I tried to redeploy Avast Endpoint Protection Suite to a laptop on our network that had been infected. The deployment failed in mid process and now I cannot redeploy since the avast Remote Install Service is on the laptop.  I cannot delete the service from the command line (Access Denied).  Any ideas on how to get a clean deployment?

run the ASWCLEAN.EXE tool that you can find on the avast website
