Sorry, my explanation is duff!
Set up your program to be started at 120s, use the '!' exclamation mark button on the right to see it starts the app.
Now for the delay:
Choose Add Program - not the same one a new one. Choose time delay seconds. The path box is greyed out. enter 120 in the parameters box. Press OK.
Now in the list use the Up button to move the delay above your app.
in the list for that section you have a wait for 120 and an exe startup below.
Again press the '!' button.
The app should wait for two mins then start up.
Instead set for 12 seconds to test it quickly.
