A method is disclosed which allows running liners with external casing packers on coiled tubing in a single trip. The compact design afforded by being able to support the liner near its lower end adjacent the lowermost external casing packer allows for a combined overall length of running tool and inflation tool short enough to fit into a standard lubricator.
