Load an exe file and set a variable from web page

_x000D_ _x000D_ I have recently been making a game in Unity (C#) and at the start a variable is set to a number. The number is a seed which is used to generate a 2d world out of blocks. This means that if the number is 5 then it will generate the same world for everyone using the seed 5. I would like to upload seeds to my webpage so when a user clicks a button, the compiled unity application (.EXE) opens and the "seed" variable is set to a certain number depending on which button is pressed. For instance I could make a button which loads the program with the seed variable set to '5', or I could load it with the seed variable set to number '8'. I am wondering if this is possible due to the file being complied and if so how would I do it? I have the code to load a .EXE file here: Click me Sorry if I am a bit too specific or confusing, this is my first post.
