Can someone help me with my Portable Apps Suite not launching self-made programs?

I wanted to get WinRAR and Project 64 to appear in my Portable Apps Suite tray. I tried just copying and pasting the portable version of WinRAR in there, but there were about 3 EXEs, and they would all appear in my Portable App tray. So I went about writing a bat file that would do the same, so I could just convert it to an EXE and have just that one display. Everything went fine- I wrote the program, compiled it, etc, and it worked great! But, when I started up the Suite's tray and launched it from there, it didn't. Anyone know why?

Oh, and in case you couldn't follow that poorly-written question, here's a link to a video:

Thanks for your help! (In case you can't read the error text, it says that WinRARLauncher.exe can't be found, even though it can be launched from Windows Explorer)
