Hi All,

I develop a website to Publish the Courses in the form of Word.
that is running good on local

i put that on a server for testing purpose
thats also running fine

Now i put that on Live
But I am unable to Publish the Course now.

I m using these dll's
Interop.Microsoft.Office.Core.dll
Interop.VBIDE.dll
Interop.Word.dll

and the problem is in this line :

oDoc.Shapes.Range(ref i).GroupItems.get_Item(ref j).Visible = MsoTriState.msoFalse;

while this line is working fine on other two servers

If i comment that line
then its work fine on Live Server also

Can someone suggest me regarding that.
