title: Excel Programming: Exception from HRESULT: 0x800A753F at Microsoft.office.Interop
body: <p>I have an application which opens,reads and creates Excel files. The app has been written in C#. The error named in the title does not always show up, sometimes it is working as intended.</p>
  
  <p>May be someone can point me to the cause of the error. Googling did not make me smarter on this one. By the way, is there some kind of overview of HRESULT codes for Excel interop?</p>
  
  <p>Thanks a lot</p>
