Hi,
Thanks for posting in the forum. You will need Azure Virtual Machine in order to use our product. This is because EO.Pdf makes numerous system level API calls and those are restricted in an Azure environment unless you use a virtual machine, which gives you full control over the system.
Please feel free to let us know if you still have any question.
Thanks
