Developers do not have to provide installation service, unless such service was agreed upon when purchasing the product.
If a developer isn't supporting their product, or is causing some sort of problem, you should contact a moderator (disclaimer: I'm a moderator) or administrator. You can also report the purchased products, or file a dispute in the forums. But posting a comment here isn't one of those solutions.
