In one the windows app which I have developed has a html editor. In my local machine which runs on Windows XP the application works perfectly, but when someone install on a clean XP system and try to modify a hyperlink from a image it throws an exception: Exception from HRESULT: 0x800a0256.

I did lot search on google but no luck with that.
 So I try apply latest patch still not working.

And here is the solution:

1. Install windows office 2003/2007

2. Install Office 2003 Add-in: Office Web Components

But I am still not sure what's cause that. Please let me know If you know why.

Notes:

1. The solution is not working when the system is 64bit, I am still working on that.
But it's works for all 32 bit windows system. I try windows XP pro, Vista Ultmate, win7 Enterprise
