EC PRO: Installing ECAP Pro when SP 3 & MSXML 6.0 SP2 cannot be removed

Issue: During installation of SQL Express, it errors out during the MSXML parser, workstation, and server components. This is turns fails the install of ECAP Pro and SQL Express. This occurs on a machine with Service Pack 3 and MSXML 6.0 Service Pack 2 already installed and you are unable to remove them.

Solution: The install of SQL Express fails due to the presence of the new version of MSXML 6.0. Once this is removed, the installation proceeds normally.

  1. Make sure all the lingering components/install files of ECAP Pro and SQL Express are removed from the computer.
  2. Download the following file: msicuu2.exe  (Windows Installer Clean-up) from the following link: Windows Installer Clean-up .
  3. Install the Windows Installer Clean-up and run this program from the Start menu.
  4. Highlight the file MSXML 6.0 SP 2 and click on remove button. Now click on Exit.
  5. Go back to the ECAP Pro install file and double click to re-run the EnergyCAP installation.
