我的c＃应用程序的发行版在其他计算机“ Microsoft Office Interop Excel”上不起作用

Question

I tried to release my project on c# and got its setup file. I used it on my own laptop and everything works. But after installing the app on other machines, I get the following Error: the COM-Object from Type: System___ComObject cannot be converted to the interface "Micorsoft Office Interop Excel" Application .

Do you guys have any idea, what does that mean?

Answer 1

您的代码正在尝试将Com对象转换为Microsoft.Interop.Excel.Application或将其类型转换为实际上不是Excel.Application对象。
