Having used Technic Launcher fine on my Win 7 PC for many moons, I have just tried to open it on my Win 8 PC as I am currently in Amsterdam (normally UK.) I download the exe (2.23MB) but when I try to open it I just get the error 'The file or directory is corrupted and unreadable' Java is up to date Tried compatibility settings Tried downloading the file in different ways Minecraft is fully up to date PC surpasses all minimum and recommended requirements Any help appreciated
