I have downloaded minecraft.exe, and it opened as soon as it was done downloading, my problem is, I see no way to open it again if I close out of it. (Also, my Operating System is Windows 10). I also cannot find it in my downloads folder, or anywhere it is like I never even had it. And, I did not delete it.
Yay! I fixed it! Come to find out I am an idiot, I did not click save while downloading! I just deleted the .exe and installed the regular one. (I tried the regular before but it did not work, so I thought I needed the .exe) Thanks for the suggestions! :)
