CAUTION : We strongly advise against downloading and copying ProjectMUI.xml to your appropriate Windows system directory. Microsoft typically does not release Microsoft Office Project Professional 2010 XML files for download because they are bundled together inside of a software installer.

An incorrectly installed XML file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
