WinGRASS errors

Due to the varieties of MS-Windows versions existing, a series of problems with the WinGRASS Installation have been identified (and solved):

Q: Error message "The ordinal 63 could not be located in the dynamic link libexpat.dll."

A: You have likely an old "libexpat.dll" in your directory %WINDIR%\system32 (or %WINDIR%\sysWOW64). Try to rename that file (or delete after backup). Then winGRASS should work.
