Microsoft Office Excel cannot access the file

Microsoft Office Excel cannot access the file 'C:\inetpub\wwwroot\AminoScience\OutFiles\Diet_Report_6c0dd8c3-5864-4c8a-9181-48b0e67cea96.xls'. There are several possible reasons:

• The file name or path does not exist.
• The file is being used by another program.
• The workbook you are trying to save has the same name as a currently open workbook.

This solution is ...

・Windows 2008 Server x64

  Please make this folder.

  C:\Windows\SysWOW64\config\systemprofile\Desktop

・Windows 2008 Server x86

  Please make this folder.

  C:\Windows\System32\config\systemprofile\Desktop

  ...instead of dcomcnfg.exe.

This operation took away office automation problems in my system.

A Desktop folder seems to be necessary in the systemprofile folder to open file by Excel.

It disappears from Windows2008, Windows2003 had the folder,
and I think it cause this error.
