Hi chungch
Thanks for your post.
Can you please retrieve the diagnostic log of the AccountRight file after attempting to export to excel, if you open the error log, can you see a Microsoft.Office.Interop.Excel._Application error ? If yes, generally this error means that when a program such as AccountRight asks which version of Excel is installed, the wrong version is being reported back causing a communication problem and errors between the programs.
This can happen when different versions of Office/Excel may have been previously installed on the computer, and components/values are left behind. This type of error can be fixed by one one of the following:
Please let me know how it goes.
