To make a long story short I'm posting the solution here, credit goes to H Ogawa

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.
