I could help you put together an NSIS installer for this, if you are interested.
I am not a disabled person so I don't know if someone who needs eye tracking needs an installer or not, but I know that installers make programs MUCH easier to install!
tell me if you need any registry entries created, or ini files made, or if you need a certain version of .net distributed with this, or require java (can't distribute java, and I am not sure how to detect yet, but I will figure something out).
If you prefer innosetup, I can't help you there. some say it's easier. NSIS is like macro assembler but higher level and it works with DLL's.
