Hi, after buying a professional license, and copying and pasting the data in the Ccleaner registry, which arrived in the mail, it gives me ERROR 12045 and tells me that the license is wrong or invalid, I proved installing Ccleaner PRO and Ccleaner Free to upgrade to PRO, and in both, it gives the same error, I sent an email to Ccleaner support and only a robot answered me, I really expected more from this company
