We are using EO.PDF to generate PDFs out of an HTML template, and it is working on all but one of the Windows 10 developer machines. All machines have the same OS images, security patches, .NET versions, and versions of Visual Studio, and all users are in the same security groups. Regardless what we have tried on that machine, it will not work. I have downloaded and installed the latest build on that machine, and am unable to even run the demos. I am an administrator on this machine when trying to run the demos, I have tried running 'as administrator' as well. We have tried with disabling and even uninstalling all antivirus software on the machine, it makes no difference.
The error when starting the EOPDFDemo is:
Windows host process (Rundll32) has stopped working.
When debugging Rundll32, the error seems to indicate a possible permission issue:
“Exception thrown at 0x777C304D (ntdll.dll) in rundll32.exe: 0xC0000005: Access violation writing location 0x00000000.“
When trying to run EOWpfDemo is:
System.Windows.Markup.XamlParseException: Initialization of 'EO.Wpf.MenuItem' threw an exception. ---> System.Exception: Can not find or automatically create eowp.exe. Please place this file in the same directory as EO.Base.dll and make sure they are the same version. This file is needed if your application does not have sufficient permission to read Windows system directory, or you have EO.Base.Runtime.EnableLargeAddressSpace set to true. Access to the path 'C:\Users\<user>\AppData\Local\Temp\eowp.17.2.43.0.exe' is denied.

Hi,
This does appear to be a permission issue. You may want to find out why your application does not have permission to access "C:\Users\<user>\AppData\Local\Temp\eowp.17.2.43.0.exe". This is your current user's temp folder and your application should have unrestricted read/write access to this folder. Without being able to access this folder, a lot of things can go wrong --- for example, the browser engine will store cookies/cache in this folder at runtime, so if it can not write this folder, it will definitely crash.
Thanks!

I am running the app under my account, and as administrator, and have verified that my account has full permissions on the folder. Under debug, I am also getting the following error:
'Failed to create child process, Win32 Error: 5'

Windows error: 5 is ERROR_ACCESS_DENIED.
Regardless how you run your application under what account --- you need to resolve the underlying permission issues. Our application basically just pass the OS error code/.NET framework error message up. We do not create those code/errors. So if the error message clearly indicates a permission issue, you will need to resolve that first. We are not in a position to troubleshoot permission issue for your system not only because they are out of the scope of our support, but also because they are out of the scope of our expertise. So your best option is to find your system administrator to resolve such issue for you.
