Problems with using an activeX

[peace2007]

Hi Everybody,

I'm using a prep-written Activex in my C# asp.net application. But when I try to call its functions (Global.vaxClientVoice.SetLicenceKey("TRIAL-LICENSE-KEY"), following exceptions is fired:

System.Runtime.InteropServices.COMException was unhandled by user code
Message="Catastrophic failure (Exception from HRESULT: 0x8000FFFF (E_UNEXPECTED))"
Source="mscorlib"
ErrorCode=-2147418113
StackTrace:

at System.Web.UI.Control.OnLoad(EventArgs e)
at System.Web.UI.Control.LoadRecursive()
at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)

What does it mean and how I can resolve it, please?

have you googled the error message and what a System.Runtime.InteropServices.COMException is? i would start there.

Could you take a look at this:

Actually I've added VAXBROADCASTCLIENTOCXLib.dll as a reference to my web application and have already registered the related ActiveX.
It's concluded from the discussion in the above link that it should be added to the main form but how I can do this in a web application? Actually I've added to a code behind page: default.cs
