Update not working on CCleaner Professional 64 bit

The upgrade function is no longer working for me.

I am no longer asked where to save the upgrade file and I cannot find it.

It does not install automatically.

How do I upgrade now?

Since you have a registered Pro version, you can log in to your account on the Piriform Support page and raise a support ticket with them on the matter.

That may be quicker getting priority support from them instead of from the community forum here.

Until resolved, all downloads are available from the Piriform website.
