I am not sure what the problem is. A simple installer would be no slower than a zip file.

A good installer is also a no brainer. Open exe, next, next, next, and final screen launch app. Then when you are done testing go to "start menu" and click uninstall.

And at least you you know that all the elements of the program are going to be the correct place.

However, I would agree that an installer in Spanish is not on. All installers that I have ever used have language support.
