EO.Pdf.dll ver. 15.3.22.0
EO.Base.dll ver. 15.3.22.0
Windows 10 1909 OS Build 18363.535
IIS 10.0.18362.1

STR
1. Create ASP.NET Web Application (.NET Framework) via Visual Studio
2. Add
Code: C# 
var memoryStream = new MemoryStream();
EO.Pdf.Runtime.AddLicense(license);
HtmlToPdf.Options.PageSize = PdfPageSizes.A4;
HtmlToPdf.Options.OutputArea = new System.Drawing.RectangleF(0.5f, 0.5f, 200f, 200f);

HtmlToPdf.ConvertHtml("<strong>blah-blah-blah</strong>", memoryStream); // <- !!!

memoryStream.Position = 0;
var result = memoryStream.ToArray();
HtmlToPdf.ClearResult();

3. Deploy

At the first run, these processes:
rundll32.exe c:\windows\SysWOW64\rundll32.exe --eopfd
rundll32.exe c:\windows\SysWOW64\rundll32.exe --eoim
are displayed in the task manager with the status Suspended
After that, System.Exception Failed to resolve LoadLibrary is thrown.
Subsequent calls throw System.InvalidOperationException No process is associated with this object

Hi,

This is because you are using an older version of EO.Pdf that does not support newer Windows. Please try to update to the latest build and it should resolve the issue for you.

Thanks!

Windows 10 1803 OS Build 17134.1184
IIS 10.0.17134.1
The code above works fine.
Also via IIS Express, the code works on Windows 10 1909 OS Build 18363.535 too.

Do you mean the latest build of the latest version?
Because I've tried the latest build 15.4.18.0 of the 15th version and the problem still exists.

Hi,

You will need to use the latest build of the latest version. Microsoft has changed a few things through different channels. Sometimes through a major update and sometimes through a minor Windows update, both in Windows 10 itself and other version of Windows such as Windows Server family. So you can not determine it simply by Windows 10 version number.

Thanks!
