It worked! Thank you, Hazelnut.
Pity that Piriform Devs appear to be unprofessionally concerned about the quality of their code.
Why would a customer pay for a product offered for sale when Piriform appear unconcerned whether it works on a platform for which it is being sold.
Hello
Running Mac High Sierra 10.13.6
The last two versions of CCleaner will not function on my Mac. I have just downloaded the latest version. Same problem.
Once downloaded, the app sits in the bar and will not open.
Can you please help?
