An anti-interference system for an electric machine comprises a single-piece or multi-piece housing component and a single-piece or multi-piece shielding component. The body includes a nozzle mounted thereon and a valve mounted thereon and operable to adjust the rate at which gas leaves the nozzle and hence the intensity of fire generated thereby. The method can include specifying an installation package for a software product as a source repository and specifying a target repository in a target platform hosted by at least one computing system.
