I inadvertently installed the Windows 7 X64 version of Macrium Reflect (paid version) on a computer running Windows XP Professional X32. The program does not appear to function correctly, but I cannot remove it since it does not show up in Add/Remove Programs in Control Panel and does not appear in the list of Programs above the Start button. I tried the Windows Installer Cleanup but it does not show the program. How can I remove it? I do not want to make the computer unbootable.
