I'm attempting to reinstall Sky Demon on my Windows 8 PC after it locked up irretrievably and have to be wiped and rebuilt. When I get to the stage where I'm asked for my login and password, I get the following message: 'Failed to write the licence file to disk. Please check that the file below is not write-protected and try again'. As the installer has clearly just written that file it seemed unlikely to me that it could be write-protected, and so it transpired: no write protect. So what gives?
