Pdfium_x86.dll from PDFium.Windows does not work

Hi, 

I am using PdfumSharp quite a long time without any problems. But recently, I have encoutered problem on PC with Windows 7 x86 (32bit). After lots of testing I have tried to replace pdfium_x86.dll with the one externally downloaded (nuget package PDFium.x86) and it is working. So I think that this DLL that is packed in PDFium.Windows is somehow corrupted.
