Some years ago I obtained Xtreme Photostory 8. Later I purchased an Upgrade: Magix Photostory 2016 deluxe. For various reasons, I have only just installed the Photostory 8 on my Windows 10 computer. I have been trying to install the upgrade but it refuses to load, halting with a messgae that refers to 'en-GB'. Can you help to sort me out?
