[Run] section will not work.

The welcome text use "msgWelcomeLabel1" and "msgWelcomeLabel2" which you can't edit inside a isl file because they are "hard coded" somewhat (at least I did not found the strings anywhere), but I think maybe you can change the caption of it with "msgWelcomeLabel1.Caption := abc"

Edit: I talk bullshit. I forgot that "msg" before the label name means something which I forgot in the meantime...

The label name which you are looking for is "WelcomeLabel1" and "WelcomeLabel2" in the *.isl files.
