I have a 1-yr license for CCleaner Pro, but I would now like to install the software on an additional computer. I understand that a Pro Plus license would allow this at a reduced price than two separate Pro licenses, but I can find an easy way to upgrade my current license. Please advice. Thanks.
It would probably be better to contact Piriform direct for info about this.
