This is just the patch for CLIP Studio Paint EX v1.11.0 and nothing else. 1. Overwrite CLIPStudioPaint.exe from "C:\Program Files\CELSYS\CLIP STUDIO 1.5\CLIP STUDIO PAINT\" or wherever you installed it, with the CLIPStudioPaint.exe from this folder. If you need the installer, just grab it from [here](https://www.clipstudio.net/en/dl/), and make sure it's the "CSP_1110w_setup.exe" one.
