AxHost

[=?Utf-8?B?WWFlbA==?=]

I have com a add-in for outlook 2003 in c# vs.net 2003.
there I add this class for display icon in my add-in button:
In some computer this add-in running currect, but in one computer
this add-in not runing..I think it's something about this topic (AxHost).
Do you have any suggestion ?
This works on the majority of desktops less one computetr.
I don't get error, I just not see my addin.

public class MatarotHost : AxHost
{
public MatarotHost() : base("02FD5840-C1A3-448E-8310-98611DF58281"){ }
public IPictureDisp GetIPictureDispOfPicture(Image image)
{
return (IPictureDisp)MatarotHost.GetIPictureDispFromPictu re(image);
}
}

Why I don't have this option in AxHost ?
AxHost.GetIPictureDispFromPicture(image);
I have only MatarotHost.GetIPictureDispFromPicture(image);
I tried all these: What is the currect method?

// public static new stdole.IPictureDisp
GetIPictureDispFromPicture(System.Drawing.Image image)
// {
// return (stdole.IPictureDisp)MatarotHost.GetIPictureDispFr omPicture(image);
// }

// public static stdole.IPictureDisp ImageToIpicture(System.Drawing.Image
image)
// {
// return (stdole.IPictureDisp)MatarotHost.GetIPictureDispFr omPicture(image);
// }
