Understanding why an installer was rejected

I’m interested in writing installers, and I tried my hand at updating the (currently non-functional) non-steam Yume Nikki installer. About two weeks after submitting a final edit, the submission was removed from the page without further notice.

It is understandable if the installer was not of publishing quality, but I am uncertain of what element(s) may need improvement. As such, I am curious about what the best approach would be to understanding the rejection process.

In short – What is the optimal route for understanding why an installer was rejected?
