Hi,
What is the detailed error message?
Is the exe file deployed by yourself? If so, how did you publish it? With ClickOnce?
It seems your problem is more related to Visual Studio Tools for Office, if so, it will be more appropriate to ask your question at Visual Studio Tools
for Office (VSTO) Forum.
So please provide more details for your question.
Regards,
Stanly
