incomplete Update of CCleaner Professional

Hi, I'm a first time user of this forum. I went to the Support page of Piriform and it lead me here. Thanks all good.

I'm trying to update my CCleaner Professional and I keep getting a message " CCleaner64.exe wont open and CCleaner\branding.dll wont open".

I went into the setting of Malwarebytes and turned off Ransomware Protection as suggested but it made no difference.

Has anyone had to deal with this? What's the fix or work around?

It's a common issue (your post is the second today) and is caused by CCleaner still running in the background, as CCleaner64.exe is still running the upgrade can't replace it.

Try the steps given here:
