Component Pack installation failure

The installation program is trying to use the wrong compiler path for D2010.  The generated error log file shows this near the top:

-------------------------------------------------Initializing setup for Delphi 2010-------------------------------------------
D2010 found
Correct Delphi / C++ Builder Environment found
Delphi 2010 selected for installation

So clearly it's finding my D2010 installation (looking in registry perhaps?)

But later uses the wrong path:

COMPILE PATH   :   C:\Program Files (x86)\CodeGear\RAD Studio\7.0\bin\dcc32.exe

Instead of the proper path

C:\Program Files (x86)\Embarcadero\RAD Studio\7.0\bin\dcc32.exe

This is the default installation path on an x64 machine for Delphi 2010 from Embaradero, not CodeGear.

This means there is something incorrect in your registry.

HKEY_CURRENT_USER\Software\CodeGear\BDS\7.0\RootDir should hold the correct path to the Delphi install folder.
