Since I have got a new laptop, I am trying to download an installer of Camtasia Japanese version. However, I cannot find the right installer. when I downloaded the installer from https://www.techsmith.co.jp, it says the licence key I've got is not valid. Interestingly, it worked when I downloaded an English one from https://www.techsmith.com/download/licenses/camtasia/9, the key worked. I have no clue what is going on. Anybody can help?
