Installation of Second Life will gives errors and fail if it cannot find MSDMO.DLL.

This library does not come with Windows 2000, it ships separately with Windows Media Player 7 or higher, and possibly other products.

Linden Labs should add Windows Media Player 7+ or other alternative dependencies on the system requirements document.

WMP 7 isn't a dependancy under Win98, so I don't think it's a dependancy under Win2k. Something else is probably going on.

The dependency is on MSDMO.DLL (Microsoft DirectShow), not specifically Windows Media Player. (I edited my post but the thread topic didn't change). MSDMO has a variety of ship vehicles, it shouldn't be difficult to find out which.

It's possible it also ships with DirectX 8+, and I did not have that installed either -- although I thought I did, as Windows Update had just given me a patch for DirectX 9. I installed Media Player 9 (which did give me MSDMO.DLL) and then upgraded DirectX 9b before reattempting Second Life.

In any case, the installer should say "Requires XXXX to be installed first" rather than say 'Cannot find dynamic link library MSDMO.DLL in search path c:\winnt\system32;..."

DirectShow is part of DirectX, which is listed as one of the system requirements.

Indeed perhaps I did not have DirectX 9 installed.

I did have DirectX 9 Hotfix - KB839643, installed by Windows Update, so I thought I did.

In any case that means the Second Life installer is not checking the DirectX version, or there is an error with its detection code.

From Microsoft:

How can I detect whether DirectShow is installed on a given machine?

Call CoCreateInstance to create an instance of the Filter Graph Manager. If this call succeeds, DirectShow is installed on the machine. The following code shows how to do this:

IGraphBuilder *pGraph;

HRESULT hr = CoCreateInstance(CLSID_FilterGraph,
NULL, CLSCTX_INPROC_SERVER,
IID_IGraphBuilder, (void **) &pGraph);

You should reinstall DirectX.

If you have a dependancy I would suggest a rehabilitation clinic.
