POSystem.DllNotFoundException: Unable to load DLL. No errors in Dev machine but error in target machines
text
Body
copied!<p>I built a C# application with WPF on Visual Studio 2012 that uses C++ DLL and targets .NET4.5. I have two projects running, one for the C# project and the other for C++ DLL project. I released both projects into a folder that has a <code>.exe</code> for C# and a <code>.dll</code> for C++ in the same folder.</p> <p>I run them on my machine where they were developed and everything works fine. I run the <code>.exe</code> in other machines and it throws this exception:</p> <blockquote> <p>System.DllNotFoundException: Unable to load DLL</p> </blockquote> <p>It's not recognizing the DLL that is in the same folder. </p> <p>I tried many things and nothing seems to work. I followed the solution in <a href="https://stackoverflow.com/questions/2093485/system-dllnotfoundexception-unable-to-load-dll-on-window-2003">this post</a> but nothing worked.</p> <p>The Dev and Target machine are identical. In Dev, Visual Studio 2012 is installed, but that's the only difference.</p> <h2>Code:</h2> <h3>C#:</h3> <pre><code>[DllImport(@"Wireless.dll", EntryPoint = "?cert_exists@certificate@CertFuncs@@SAHHPBD@Z", CallingConvention = CallingConvention.Cdecl)] static extern int cert_exists(int store, [MarshalAs(UnmanagedType.LPTStr)]string cert_str); </code></pre> <h3>C++:</h3> <pre><code>static int __declspec(dllexport) cert_exists(int type, LPCSTR cert_str); </code></pre> <hr> <h2>Update:</h2> <p>If I install Visual Studio 2012 on the target machine, everything works fine. If I remove it, the application crashes again. Any ideas on what VS is adding that can make the application work?</p>
