CCleaner Pro "Lifetime" Licence - why has it expired? in CCleaner Posted May 3 · Edited May 3 by Dave CCleaner "members-only" discount link removed Very very disappointed with Piriform. Like others, I'm now also getting the message that the registration key of my CCleaner Pro is no longer valid - despite being used on a single PC all the time, therefore not in breach of any t&c's. I asked Piriform support to sort out my licence issue and this is the response: Quote "it would seem that our licence management system recently automatically disabled your licence for overuse when it was flagged as having been used on 13 distinct machines - which is naturally problematic for a single PC home-use licence.We understand that this sort of thing can happen over time, and a couple of options for you would be: If you only need CCleaner for one PC I can create you a complementary replacement licence - although note that this would only last for 12 months and then need to be renewed at the prevailing rate. If you need CCleaner for multiple computers, we have an offer on at the moment on 2 year licences of the 3 PC CCleaner Professional Plus bundle here [private link removed] If neither of those options appeal, there is always the free version of CCleaner available from https://www.ccleaner.com which of course has no limit on the number of PCs. If the first option works for you then let me know and I can get that created for you." They clearly want one-time licence holders of Ccleaner pro to start paying. I'm not even going to take up their offer of a free 1 year licence. Goodbye Piriform, won't be touching any of your products ever again....even if they come with so called lifetime/one-off licence fees.
