The MFC 7.1 run-time libraries that ship with MATLAB are visible to other applications you may have because the matlab/bin/win32 directory is added to your path at installation time. This can cause problems when uninstalling or re-installing MATLAB because another application may have one or more of these DLLs in use at that time, thus preventing the MATLAB installer from being able to remove it.
To work around this issue, remove matlab/bin/win32 from your Windows path and reboot their system before attempting to uninstall or re-install MATLAB. By removing this directory from the path, other applications are no longer able to see these DLLs.
