On some Windows systems, the installer may fail to properly associate
.pptx files with Sikuli Slides. When this happens, you won’t find Sikuli Slides as an option under the Open With menu. These are the steps you can follow to make this association on your own.
Select “Open With”
Select the “Sikuli Slides” directory
Select the “sikuli-slides” program and then select “Open”
You are done! Your slides should be executed now. Next time when you try to open an
.pptx file, Sikuli Slides will become available as an option.
