Zusammenfassung:	An installation apparatus for installing a liner in a subterranean formation includes a housing having an internally arranged flexible member operatively connected to a bore-forming device at one end and to a control module at another end. An opening is arranged in a housing wall through which the flexible member and device may be passed. A liner is arranged around at least a portion of the flexible member between the opening and a first support member. The first support member is arranged to move inside the housing in a direction towards the opening, and a second support member is configured to movably support at least a portion of the flexible member in the region between the control module and the first support member. A method of installing a liner in an inverted drainhole is disclosed.
