This is because the MSI package records only a single package name for
all CMake versions.  Each installation is assumed to replace any existing
installation of the same package.  Linux distro package tools do the same
thing.  One can use the .zip files to have independent versions not managed
by a package system.

The type of prompt should make no difference.  The installer provides
an option for adding the CMake installation to your system PATH.  MSI
takes care of reversing effects of the removed installation, so that
may have removed it from your PATH.
