updated my license and received new code if i replace it will the program retain both keys or will i lose 70 days on current code
If you have used the same email address, and have less than 90 days left on the old licence, then the time left will be added to the new licence so that you don't lose anything.
This happens automatically but it's done in batches twice a day so it may not show up straight away. Just give it time.
If you used a different email address, or had more than 90 days left, then it's assumed that you wanted a second licencefor a different machine so they will not be merged automatically.
You can still get them merged so that you don't lose any time by emailing support@ccleaner.com and asking them to merge the 2 licences.
