Excel programming: exception from HRESULT: 0x800A03EC. at Microsoft.office.Interop

I created a small application that opens, reads, and creates Excel files. The application was written in C #, and I do not know why I get this error message when the application runs on the same computer. I run the same application on my computer and I have no problems.

Can someone help me and tell me why this error occurred?

thanks

First of all, I suspect that HRESULT really was 0x800A03EC (it is very important to report the exact number if you say error codes ;-)).

For example, if you have a script trying to set a cell to "==== Fake Note by: fakeuser 6/23/14 14:41", then it will throw an error. To get around this, check the value of the leftmost character to see if it has "=", "+", "-", "/" or "*". If so, just add a space as the first character and the text will be added correctly.
