CM 1.6.8 on Windows no auto stop uninstall previous CM

Just an observation, looks like a very small glitch in the CM 1.6.8 windows msi x64 installer.
It detects a previous version 1.6.7 running, but instead of “trying to stop and uninstall” the running version, it now displays a prompt requesting to close the running app.
Not a big deal but different from all previous upgrades. Btw, upgrade went ok.
