Web Authoring Component install fails when installing Visual Studio 2008

While trying to install Visual Studio 2008 Team Suite in my Windows XP Professional system it kept failing when installing Visual Studio because it couldn't find the Web Authoring Component (after installing having just successfully installed it).

I've looked around for occurrences of this problem but I didn't find anyone with such a problem.

I tried to install Visual Studio several times, successfully installing the Web Authoring Component (you can find it on the DVD - \WCU\WebDesignerCore\WebDesignerCore.EXE) before, but it always failed in the same step and for the same reason as before. And, even more strangely, after that, the Web Authoring Component was no longer installed.

I went through the install log file (%temp%\dd_depcheck_VS_VSTS_90.txt) and found this:

Microsoft Visual Studio Web Authoring Component ==  
    This component uses the FileRegVerCheck version check method. It will compare a given version against the version of a regkey on your machine.
    Registry key being interrogated: HKLM,SOFTWARE\Microsoft\Web Designer Tools\1033; Value: InstalledVersion; Version: 12.0.4518.1066.
    Version on user's machine:    12.0.4518.1064
    Version to be installed:    12.0.4518.1066
Microsoft Visual Studio Web Authoring Component == Component to be installed.

I went to the registry and changed the value of the installed version to the one expected by Visual Studio installer and it installed it with no problems. And looks like it's working fine.

What strikes me as the most strange is not the fact that the component on the DVD has the wrong version. What strikes me the most is the fact that I had already installed Visual Studio using the same DVD without any problems.

The Web Authoring Component installer uses a Office 2007 wrapper. I wonder if that was the problem.
