That is not how it goes.
If you buy a product in the marketplace, lets say version 1.0, and the 3rd party developer is already in version 1.3 and you cannot get it from the marketplace nor the developer, but you can go to a pirate website and get the newest version. While I do not approve that practice, at least in Spain it is legal to do so, since you own and have payed for the original product.
Anyways, my point is you should not be forced to do that, since it is dangerous for your PC and the issue could be easily solved if the marketplace updated instantly the products.
