not loading

My CCleaner professional is not loading. I have uninstalled and reinstalled. No good.

How do I fix it?

What anti-virus are you using?

Trend micro. I have had them both working for over a year.

There is an issue with some AV's blocking v5.65 at the moment, Trend Micro seems to be the most prominent.

White listing CCleaner in Trend is working for most.

There is an official response here:
