[cannot run product at this location]

Thanks... that worked.  I guess they could have worked a bit harder to hide it.

[cannot run product at this location]

I had to reinstall CCleaner after received the error "cannot run product at this location".  I removed CCleaner including the associated plists and installed Version 1.17.603.

There is not an option to activate the product (current subscription valid until 04/22/2020) only upgrade.  Is there a way to acrivate or do I need to purchase a new license?

[Where to enter Product Key]

I was receiving an error that I could not use the product at my location, so I removed CCleaner and reinstalled it (installed version is now 1.17.603), on a Ma. 

There is not an option to enter my current Product Key (valid until 04/14/2020), only Upgrade.

Is there a workaround or do I need to purchase the product again?
