# How to Get the Best Engineering Support for IronPDF
Thank you for taking the time to get IronPDF working properly. We have a dedicated team of engineers who continually work to improve IronPDF with new releases. Updates are often being published 1 or more times a month.
To help us help you, we need to categorize the issue you are having into one of the following types:
## Exceptions and Bugs
If you have a report of a fatal error with IronPDF that stops you from using our code, we want to know!
_The clearer the bug report, the faster it will be resolved._ Please report it by following the instructions on the [Exceptions & Bug Reporting Page](/troubleshooting/engineering-request-pdf/) to isolate the issue and provide the log files we need to help you.
_If your issue is in the following list of hot issues - a solution may already be available:_
Exception: ["IronPDF Unable to Render PDF"](/troubleshooting/timeout-while-rendering-pdf/).
## Deployment Issues
If your solution works locally but fails when deployed to another machine, we would love to improve our support for that platform and appreciate you making [a bug report with log files from the machines where the issue occurs](/troubleshooting/engineering-request-pdf/).
There may also be a knowledge-base guide for setting up this software on your platform, such as [Amazon AWS](/troubleshooting/aws-lambda-amazon-linux-2/), [Azure](/how-to/azure/), [Docker](/get-started/ironpdf-docker/), [MacOS](/how-to/macos/), and [Linux](/get-started/linux/).
_If your issue is in the following list of hot issues - a solution may already be available:_
- _System.Exception: Error while deploying Chrome dependencies._ Please install [Visual C++ Runtimes](/troubleshooting/visual-c-redistributable-for-visual-studio-ironpdf/).
- **System.Exception: Cannot Initialize IronPDF, Pdfium, or IronInterop** is also caused because [Visual C++ Runtime is not installed](/troubleshooting/visual-c-redistributable-for-visual-studio-ironpdf/) by default on Windows.
## HTML to PDF Rendering
We have a detailed [tutorial on HTML to PDF rendering](/how-to/pixel-perfect-html-to-pdf/) techniques that we recommend to all users. A unique advantage of IronPDF is that we use a modern Chrome browser engine to render HTML to PDF, and the behavior can be easily reproduced on a web designer's computer so that they can get you Chrome-optimized HTML, CSS, and Javascript.
If IronPDF is running slowly, we also have a [performance recommendations article](/troubleshooting/ironpdf-performance-assistance/) which has helped thousands of users before you. We also have a guide about [speeding up start-up time](/troubleshooting/initial-render-slow/).
## Licensing
Our most common questions are about licensing:
- [How to get licensed for IronPDF](https://help.ironsoftware.com/licensing/licensing/) and which license applies to your use case.
- [How to apply a license key](/troubleshooting/apply-a-license-key-in-ironpdf/) for commercial deployment is also a very common article.
If these do not apply or assist in resolving this issue, and you would like to request assistance from one of our highly trained engineers, [please follow this guide](/troubleshooting/engineering-request-pdf/) to produce the swiftest resolution.
