Getting "ieframe.dll failed to register" while installing an application built using watin?

Recently I have developed an automation application using WatiN API, in .NET Framework 3.5, for automation of an AD posting process. But at the time of installation i get an error that states this,

"Module C:\Program Files\XYZ Solution\XYZ App\ieframe.dll Failed to register. HRESULT -2147467263. Contact your support personnel."

I am using IE browser to automate the whole process. The project has been developed in Win XP, VS 2008, .NET Framework 3.5, using Watin API ver-2.1.0.1196, in C#.

The thing is that it works fine although it shows the error, but my client does not wants to get the error.

Can anybody pl开发者_StackOverflowease help me with this issue.

Thank You
