HI,
i have a very big problem.

I released a program usign assimp (the latest version). compiling the program i need to use only x64 CPU.
In my bin folder I copied assimp64.dll and add a reference for assimpnet.dll
On my pc everything works as well, but whei i install the program on my customer pc i get an error:

It seems the program could not load assimp64.dll but the file exists on bin folder!!

SOMEBODY CAN HELP ME??

Hello, not sure if this will help i also use VB.NET and created a Loader class this may help you, i also included Assimp32.dll even though it is 64bit

Code:

#Region "Assimp Loader Class"
    Public Class AssimpLoader

        Public Shared Sub LoadAssimpNativeLibrary()
            Dim assimpLibraryFolder As String = AppDomain.CurrentDomain.BaseDirectory
            LoadAssimpNativeLibrary(assimpLibraryFolder, assimpLibraryFolder)
        End Sub
        Public Shared Sub LoadAssimpNativeLibrary(ByVal assimpLibraryFolder As String)
            LoadAssimpNativeLibrary(assimpLibraryFolder, assimpLibraryFolder)
        End Sub

        Public Shared Sub LoadAssimpNativeLibrary(ByVal assimp32BitLibraryFolder As String, ByVal assimp64BitLibraryFolder As String)
            Try
                AssimpWpfImporter.LoadAssimpNativeLibrary(assimp32BitLibraryFolder, assimp64BitLibraryFolder)
            Catch ex As AssimpException
                MessageBox.Show("Error loading native assimp library! The most common cause of this error is that the Visual C++ Redistributable for Visual Studio 2019 is not installed on the system. Please install it manually or contact support of the application. Error message:" & ex.Message)
                Throw
            End Try
        End Sub



    End Class
#End Region

The other thing i forgot to mention is in your solution explorer show all items right click on assimp64.dll and choose include in project then right click on assimp64.dll choose properties Build Action = Content
and also
Copy to Output Directory = Copy if newer
