After installing Premier Pro CS6 using Creative Cloud subscription, when I attempt to launch I get "The application was unable to start correctly(0x000007b)." I had CS4 Master Suite Collection on my PC as well and attempted to uninstall it, which failed and caused me to reinstall the CS6 cloud apps again. But still same error with Premier Pro or related apps.
Moved from the Creative Cloud to the Premiere Pro forum. They will be able to help you here.
