Are we supposed to guess what the error is that you see on your screen that we can't see?

I am positively, absolutely sure that is not the error message that is being displayed on your screen. It's really not that difficult to copy and paste some text.

Does LoadFile accept a memory stream?

More to the point, does LoadFile accept a byte array?

(Based on the code posted, the MemoryStream is created but never used.)

Oops.

You could load the default web browser (most modern browsers can display PDF files) on the system with the path to the pdf file as your URL.

Rather than relying on an ActiveX control, which may not be present on your users' computers, you might have better luck using a native .NET solution.

PdfiumViewer[^] is an open-source .NET library based on Google's "PDFium" project. You can install it via NuGet[^], and it seems to be actively maintained.

If you want to stick with the ActiveX control, you'll need to check what the LoadFile method expects as its parameter. Everything I've seen suggests it wants a path to a PDF file on disk, not an array of bytes or a stream.
