[Closed] DOS Command : environement variable ignored

Hello, little issue here. I’m using DOSCommand to send a little job to imageMagick, but the environement variable is ignored, forcing me to enter the full path of the application, so something like :

"\"C:\Program Files\ImageMagick-7.0.8-Q16\magick.exe\" " + image1 +" "+ image2

when i’d like :

"magick " + image1 +" "+ image2

which works in a DOS prompt. Is there something i can do ? Thanks !
