try a system() call.

Have a look in the docs at Kernel#system .

Also have a look at the adopt-a-newbie thread.

Since you mention .exe I assume your on windows.

Have a look at IO.popen

Give it in back quotes as shown below

output = `my_app.exe`

you can also do it as

exec("my_app.exe")

exec will throw an error if the exe will not be executed, whereas
system()will return true if exe runs properly and false otherwise
