.dll file not accessible

Question

I am trying to add a dll to my project. When I do "add reference" and try to add it, it tells me :

"A reference to ... could not be added. please make sure that the file in accessible, and that it is a valid assembly or COM component".

BTW, I am trying to add g729.dll

How can I add the dll?

You must register your dll in register base before add reference

You can use Regsvr32 tool

In my case I changed the dll installation folder and lost references at visual studio. Got the file back where it was before and things works again. Thanks for your help @AghilasYakoub – Eduardo Xavier Nov 07 '14 at 14:25

If you know assembly name and version like below you can un load project and open csproj in edit mode. Then find references and add you dll reference

Example

    <Reference Include="ReferenceDllAssemblyName, Version=1.0.0.0, Culture=neutral, PublicKeyToken=5a159fbc978150a3, processorArchitecture=MSIL">
      <SpecificVersion>False</SpecificVersion>
      <HintPath>..\TempPath\ReferenceDllAssemblyName.dll</HintPath>
    </Reference>
