dllnotfoundexception

I was testing on a customer's box this afternoon which has Windows Vista (He had home, but I am testing on a Business Edition with same results). We make use of a .DLL that gets the Hardware ID of the computer. It's usage is very simple and the sample program I have created works. The Dll is This from AzSdk . In fact, this works perfectly under Windows XP. However, for some strange reason, inside our project (way bigger), we get this exception: Exception Type: System.DllNotFoundException Exception Message: Unable to load DLL 'HardwareID.dll': Invalid access to memory location. (Exception from

I have a C# application that uses SQLite and works fine on Windows. The same Visual Studio project compiles fine in Xamarin Studio, but when running I get: DllNotFoundException: SQLite.Interop.dll Despite: libsqlite3.0.dylib is in /usr/lib and also in the same folder as the executable and other DLLs . is part of the $DYLD_LIBRARY_PATH The executable and all SQLite-using DLLs have a matching <the_exe_or_dll_including_filename_extension>.config file containing: <configuration> <dllmap dll="sqlite" target="libsqlite.0.dylib" os="osx"/> <dllmap dll="sqlite3" target="libsqlite3.0.dylib" os="osx"/>

I've been trying to figure this out lately. It is working on my Windows machine, where I got SQLite from NuGet, but... When I put System.Data.SQLite.dll and SQLite.Interop.dll straight from my Windows machine into Linux server it says that SQLite.Interop.dll is not found, but I am sure I see it next right to executable. Then I tried to compile System.Data.SQLite.dll with /p:UseInteropDll=false , but with no luck. This time it says that System.Data.SQLite.dll is not found. What is this "not found" mystery? Alexandre Marcondes Use Mono.Data.SQLite.dll on Linux. Take a look at the Mono manual to

EDIT (the whole question, it was too unclear) I want to use OpenSSL.NET The OpenSSL.NET install instructions page: INSTALL Make sure you have libeay32.dll and ssleay32.dll in the current working directory of your application or in your PATH. DONE In your .NET project, add a reference to the ManagedOpenSsl.dll assembly. DONE I have put libeay32.dll and ssleay32.dll in both my bin/Debug and bin/Release directories. I have also put them in system32 . Here is my FULL code: using System; namespace ConsoleApplication1 { class Program { static void Main(string[] args) { try { OpenSSL.Crypto.RSA rsa =

So I'm using an SDK for a hardware random number generator which provides a dll called PsyREG.dll for interacting with it, as well as some c# source for using the methods from the dll. It has worked in the past, but somehow it has stopped working. My hands are a bit tied as I don't actually have access to the device in question at the moment, so I can't try a lot of things... However, here's the weird thing. The dll is there, the same place it's always been. Ahd in fact File.Exists("PsyREG.dll") returns true, and I've double checked and that's the exact same way the provided c# source imports
