I also got the Runtime Error 217 when I started my EXE on a computer on which my Delphi (Delphi 12.1) was not installed. Skia was not enabled! But VCL.Skia was automatically added to the uses list. Then the DLL sk4d.dll is required. After lengthy testing, I also found out why the VSL.Skia unit was added to my project. I used a TImage component and unfortunately used an SVG icon. When I replaced the ".SVG" icon with an ".ICO", VCL.Skia was no longer automatically added to the uses list and I was able to do without the DLL again.
