Ccleaner Professional won't update

Hi, I hope somebody can help me with my problem. My dad bought a new laptop with windows 10 home. I have installed Ccleaner Professional on it, when I try to update it will go through the download process for the update but when it get almost to the end, it just quits and won't finish.

Thank you,

Claudia

don't forget that having the Pro version entitles you to direct, priority support from Piriform, rather than this forum.

but, something to try; make sure you are getting the download from the official Piriform builds page here: http://www.piriform.com/ccleaner

instead of using the inbuilt update process, go there and manually download the file.
