Can't execute Microsoft Secutity Essentials

I don't get it.  I was having a problem with Microsoft Security Essentials, so I just uninstalled it and then reinstalled it.  The reinstall seemed to go easily enough and it executed a Quick Search with no problems nor errors.  But when I went to execute MSE manually by looking for the executable using Start ... ess enter, enter as I have usually done, I got a message saying 'Windows can't open this file'

Microsoft Security Essentials.lnk

Why can't I execute MSE as usual?

Restoring your PC to a time before you uninstalled MSE.

Microsoft Antimalware service is running and working automatically.  But I don't see MSE.  Should I?
Use Revo uninstaller (free) to uninstall it again.  Use CCleaner to do a clean up (optional).  Restart. ck  Reinstall MSE.

Do you see it in your program files?

If you click on "properties" (right click on the MSE shortcut in Start) what does it point to?

The reason I didn't use REVO Uninstaller in the first place, is that MSE doesn't show up in RU list to uninstall.  So I used control panel uninstall instead.  It seemed to work.  But MSE is not in program files either.
