Update 5.26.5937 will not complete install.

I have tried to update thru the notification email and thru the CCleaner itself with Check for update. Whenever I start the update, it downloads to approximately

55%, then the download window disappears and nothing happens. I have rebooted and retried 6 times, and it will not install.

I have Windows 7, CCleaner Professional (paid) v5.25.5902. Is this a Windows 10 only update? Thanks

Seems to be one or two server connection issues at the moment.

Give it a few hours or so and it should be sorted :)
