The [Running On Unsupported OS] message is displayed if your OS does not meet CLIP STUDIO PAINT's operation environment requirements.

CLIP STUDIO PAINT licenses are separated by [Japanese], [Traditional Chinese], and [Other Languages]. Operation environment OS changes depending on the license type.

For example, the license for the [Japanese Version] only runs on an OS set up in Japanese.

If you try to use the [Japanese Version] on a Chinese OS, the above-mentioned message will be displayed.

The message is also displayed if you are using an old OS that does not meet the operation environment requirements.

Please use the application on a device which meets the operational environment requirements.
