Runtime Error after creating object WMSServerClass --> code: 80040 dotdotslash 12/11/2008 8:32:06 AM hi.. I was trying to create a Window Media Server by using C#. So, I went to http://msdn.microsoft.com/en-us/library/ms741122(VS.85).aspx to start. I gave me a simple code of how to create a server as the following: using System; using System.Collections.Generic; using System.Linq; using System.Text; using Microsoft.WindowsMediaServices; using Microsoft.WindowsMediaServices.Interop; using System.Runtime.InteropServices; namespace CreateServer { class Program { static void Main(string[] args) { try { // Create a new WMSServer object. WMSServer Server = new WMSServerClass(); //Error here!!! } catch (COMException comExc) { // TODO: Handle COM exceptions. } catch (Exception e) { // TODO: Handle exceptions. } After I complied, it didn't gave me any error or warning. However, after I started to run the program it gave me a runtime error System.Runtime.InteropServices.COMException <0x80040154>: Retrieving the COM class factory for component with CLSID {845FB959-4279-11D2-00805FBE84A6} failed due to the following error: 80040154. at CreateServer.Program.Main(String[] args) in D:\.... My computer is running Windows Vista Home Premium with VS 2008. I previously installed windows media services SDK from http://www.microsoft.com/downloads/details.aspx?FamilyId=F26B1AA4-741A-433A-9BE5-FA919850BDBF&displaylang=en#Instructions I added microsoft.windowsmediaservices.dll (ver: 9.0.0.3693) from C:\Program Files\Microsoft SDKs\Windows\v5.0\Include\microsoft.windowsmediaservices.dll I am not sure if there is a conflict between dll component. I noticed that I have 2 different version of microsoft.windowsmediaservices.dll in my computer (9.0.0.3693 and 9.0.0.3665). If anyone got any idea of how to solve this problem, please let me know... Sorry for bad grammar

It only contains docs, samples and supports libs (like the interop DLL you copied). To get WMS, you need to install a Windows Server system (2003, 2003R2, 2008), not Vista. -- // Alessandro Angeli // MVP :: DirectShow / MediaFoundation // mvpnews at riseoftheants dot com // http://www.riseoftheants.com/mmx/faq.htm
