What to do, if you want an internal deployment: Change (optional) the following files/values: net/pflaeging/PortableSigner/i18n_de.properties HomepageURL=... net/pflaeging/PortableSigner/Version.java internaltag = "-Org" you can change anything else like texts and default logo also, ... These things are typically in i18n_??.properties or in Signatureblock.properties After this compile and package the system. The easiest way for Deployment on Windows is to take the PortableSigner-Windows.zip from your dist/ship directory anf unpack it under a directory on the PC's. It doesn't need anything else like Registry except Java and the JCE unrestrictes Extension installed :peter
