Support for Windows Vista Service Pack 1 (SP1) ends on July 12, 2011. To continue receiving security updates for Windows, make sure you're running Windows Vista with Service Pack 2 (SP2). For more information, refer to this Microsoft web page: Support is ending for some versions of Windows.


Consider the following scenario.

  • You are running a Windows XP Service Pack 3 (SP3), Windows Vista Service Pack 1 (SP1) or a Windows 7 based computer

  • You use a user name that includes a double-byte character set (DBCS) character.

When you try to install an application that uses the Microsoft Visual C++ 2005 Redistributable Package, you receive the following error message:

Command line option syntax error. Type command/? For help.


This problem occurs because the Win32 Cabinet Self-Extractor tool cannot handle the DBCS characters in the user name.
