Need help with IMG + CUE file

Hello Boulder, if you can provide an error message that can give us more information would be helpful, but first you can try moving the files into another folder in your desktop, the file path also looks too long with the Japanese characters and can be causing issues when mounting the file, also try removing from every file name the bracket ‘}’ and then mount the .img directly into Daemon tools, if it fails and is from a torrent try to check the torrent consistency in your torrent client, if downloaded directly look for a md5 or sha1 checksum and use a tool to compare them with your file, if they don’t match you have a corrupt download so download it again.

Or try opening it with alcohol 120% or virtual clone driver.

I am glad to hear that your problem is solved, your are welcome :)
