Cause:
======
This is a bug in Eclipse.

https://bugs.eclipse.org/bugs/show_bug.cgi?id=300577

Windows 7, the value of HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders\Desktop may be set in two ways:
- With %USERPROFILE% variable, e.g. %USERPROFILE%\Desktop
- With absolute path, e.g. c:\users\userName\Desktop

When the value of HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders\Desktop is set with the %USERPROFILE% variable, studio/eclipse failed to be open with the error.

Deploy Eclipse with a higher version (e.g., 3.7.0) to work around this problem.

Resolution:
=========
Update value of HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders\Desktop with absolute path(replace %USERPROFILE% with its real value)
