VMware on Wednesday launched its Fusion 4 software optimised for Apple's Mac OS X Lion.
The company's Fusion software, which is used to run Windows on a Mac, is in a dogfight with Parallels, which recently rolled out its Desktop 7 software.
Pat Lee, director of end-user computing clients at VMware, said the company's aim was to "run Windows apps like Mac ones" and use LaunchPad "to launch either one".
VMware said it would love to deliver Fusion 4 via Apple's Mac App Store, but for now a USB key is the only way to install it.
