I get an error (with loading AddIn) by opening an excel workbook

MAT
Hi.
In my C# Application I open an Excelworkbook and try to write some data to
it. The excel file has some macros,which are disabled (Macro security is
high). One of the macros try to load an AddIn by the opening of the file.
Wenn I open this Excel file normally (with just clicking on it) I get no
message.
Wenn I try to open it with C#, I get a message that says something like that
"the Installed-property of AddIn can not be found".Although I can do all
operations that I want after clicking "End" or "debug", I dont want to see
that message.
As I said all macros are normally disabled. and "Trust all installed add-ins
and templates check box" is checked in Excel file.
What should I do?
