UCCAPI.DLL " CLSID {201D2DCD-AF4F-484E-9793-56CAC5EC0C16} failed due to the following error: 80040154 Class is not registered

At https://social.msdn.microsoft.com/Forums/sqlserver/en-US/d3cfab4d-4b2b-43b8-a4da-6e46e91cd99b/uccapidll-not-registered?forum=ucclientsdk there is a question about the uccapi.dll delivered by Microsoft where there is a error:

Retrieving the COM class factory for component with CLSID {201D2DCD-AF4F-484E-9793-56CAC5EC0C16} failed due to the following error: 80040154.

Uccapi.dll is already registered. Microsoft.Office.Interop.Uccapi is also included in reference. Specifically this error is raising at,

UccUriManager uriManager = new UccUriManager();

I receive the exception that the COM-classfactory is NOT REGISTERED.

The confirmed solution is to add a manifest file to the C# project where I use VB.NET so I added a manifest file (Think it was there already) but the solution is as follows:

---

Make sure the project has a manifest file, if not the following should work:

manifestVersion="1.0">

version="1.1.0.0"

processorArchitecture="x86"

name="IMVoIPSample.exe"

type="win32"

/>

type="win32"

name="Microsoft.VC80.CRT"

version="8.0.50727.762"

processorArchitecture="x86"

publicKeyToken="1fc8b3b9a1e18e3b"

/>

version="2.0.0.0"

processorArchitecture="x86"

name="UCCAPI"

type="win32"

/>

Just replace the assembly name with the one appropriate to your project. Also, make sure that the new manifest has been selected within the project properties.

I edited the manifest file with the above but the uccapi.DLL still seems not to be registered

do I need to do the following?: "Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG))"

Error 80040154 (Class not registered exception) when initializing VCProjectEngineObject (Microsoft.VisualStudio.VCProjectEngine.dll)

I have 64 bit
