Problem installing Help of Delphi (2009 and/or XE)

I want to install Delphi documentation or either 2OO9 or XE. But I receive this message : Namespace not found on this PC ...

See the log file (debug enabled) : http://www.mediafire.com/file/2p31yh76kzt1spb/H2Reg_Log.txt

What's the so开发者_JAVA百科lution ?!

Thanks.

This probably means your installation is corrupt. Try uninstalling and then re-installing.
