Is the FREE version of cc Cleaner for Mac iOS systems available for free download in Ghana?
I've never seen them mention on the main site and download pages what country using the software is banned in. I think it's just a matter of downloading it and installing it, or at least trying.
If your ISP is using or bought old decommissioned Iran IP's you might have issues, that is if I'm remembering previous discussions about it correctly.
The sanctions list is subject to change from time to time - but Ghana is not on the list.
As @Andavari says, there have been some issues with IP addresses formerly allocated to Iran still creating problems. That would need your ISP to notify the various geoIP providers that their information is out of date, since these third party lookup lists are used by multiple software companies to ensure their legal compliance.
