Start BatterySaver when Windows start

I've downloaded BatteryServer on this site : https://archive.codeplex.com/?p=batterysaver and I want to start this application when windows start using the task scheduler. But it doesn't work and under "Results of last execution" I have the error 0xE0434F4D. If I run manually the.exe file, it works. How can I make this program run when I boot my laptop ? I don't know anything about coding so please be very precise. Edut : After a few test, the program run perfectly manually (when I double click on the .exe) but when it is lauched "by windows" via a .bat file, the cmd ou task scheduler, it doesn't work
