Can't find any reference to this problem in forum discussions.

Above problem occurred twice before when downloading and installing 'Uninstall Tool'.
Twice it was installed and removed, before allowing replacement of 'Add or Remove Programs' on third attempt.
Re-downloading , re-installing, and re-running made no change in the problem described above.
It appears everything is normal but can't utilize 'Uninstall Tool' because opening screen won't stay displayed.
