Virtual PC cannot find MSXML 6

I had a sucessfully working MS Virtual PC 2007 virtualization software for a long time. I was running a Windows Vista and a Windows 2008 Server RC0 operating systems without any problem on my laptop.

If you want to download Windows Virtual PC 2007, or Microsoft Virtual PC 6 please visit Microsoft Download Center

After I have uninstalled Microsoft SQL Server 2008 (aka Katmai) November CTP (CTP5) from my laptop, I began getting the below error message when I start the Microsoft Virtual PC 2007.

Virtual PC
Virtual PC cannot find MSXML 6.
Please reinstall Virtual PC or install MSXML 6 and try again.

Virtual PC 2007 MSXML 6 error

Actually the error message was self explaining so I chosed the simplest one, re-installing the Microsoft Core XML Services (MSXML) 6.0

You can find the installation files from Microsoft Downloads site from page titled Microsoft Core XML Services (MSXML) 6.0

After the installation of MSXML6 successfully, the MS VPC 2007 started working normally.
So be prepared for such small problems if you have installed and running MS SQL Server 2008 CTP5 and decided to uninstall the CTP5. But it seems to be quite easy to repair the problems that might arise as seen for my case.
