Excel Programming: Exception from HRESULT: 0x800A03EC. at Microsoft.office.Interop

I have created a small application which opens,reads and creates Excel files. The app has been written in C# and I don't know why I get this error message when the application is running in one computer. I have run the same applicaiton on my computer and I don't have any problem.

Can somebody help me and let me know why happen this error?

thanks

From stackoverflow
  • What OS's are on each of the machines involved? I suspect Vista on 1.

  • Nope. In both are windows XP.

  • First of all, I suspect the HRESULT was really 0x800A03EC (it's kinda important to communicate the exact number if you are talking error codes ;-)).

    What this error usually means is that one or more formula contains an error. The main reason for a formula working on one machine and not on others is usually "locale": check if that machine has different formatting settings for numbers, dates and/or currencies (comma v.s. period, etc).

  • Yes. That it is the problem. Thank you very muCh for your help. GREAT, GREAT!!!!!!

  • I had this problem and I lost many hours and this little simply post help me a lot.
