I set the "Start with Windows" check box.
The following key has been created by SC:
"Screenshot Captor"="\"C:\\Program Files (x86)\\ScreenshotCaptor\\ScreenshotCaptor.exe\" /autorun"
that seems correct.
Do you have an idea why SC does not run at Windows startup? (or perhaps, why does it stop immediately?)
Note that I have no problem launching it manually.
