When I view downloads I find an icon that looks like a piece of paper with a curled corner. It says, 'arduino-1_8_7-windows_exe'
Something in Windows has associated itself with .exe files. The download should appear with the Arduino icon. It is an executable installation and should run just by double clicking it. Is it the proper size? About 103MB for 1.8.7? If so, just try it and see what happens.Yes, it's 103 MB. No matter if I double left click or right click and select 'open with', I get that error. I don't know how to do what that error message wants.
Are you certain that's the exact filename? It should be arduino-1.8.7-windows.exe, not arduino-1_8_7-windows_exe.
