Launching external .exe files...possible?

Hey people!I'm sorry for posting something that has been talked about in a couple different threads here but, I haven't found the solution to my particular problem.I have built an e-learning program in which at a particular point the user clicks a link to launch an .exe file. Problem being, it doesn't work.I've tried the 'Launch a program/document' command along with just about every other suggestion or comment made in regards to this topic in this forum, still nothing.I'm using Lectora Enterprise Edition 2007 by the way.The .exe file is a Macromedia Projector and really isn't that big in my mind. It's 2.5MB in size, is that too big? I figure it shouldn't matter because they're launching an application file that they just have to open.That's another thing, I've read on some threads that people actually get their .exe files to open and display the 'Open' or 'Save' page that normally appears when you try to launch an application.I have it set up so that when the user clicks on an image it should launch the .exe file (in a new window) and then go to the next page within the e-learning.If anybody could help it would be greatly appreciated.THANKS
