Instal Error: "Another instalation is already running" (BUT ITS NOT!!)

Hello;

I cannot install (CorelDRAW Premium Suite.)  It keeps on telling me that there is another installation running.  I have tried every "home remedy" there is to try(rebooting, disabling Norton before installing, etc...)  Any other program that Im trying install(non-Corel) installs without any hassles.  Anything else I can try?  I am running Windows 7 (64-bit) and my laptop is pretty well-maintained with rarely(if any) problems ever occurring.  Please help!  Thanks!

  • have you checked the programs and features option in Control Panel for a Corel entry, if you see one try uninstalling it.
