It's not corruption. Think of pp as creating a self extracting executable. For a while pp installation failed for me on windows at the test phase, because rapidly creating exes which self extract and ran elsewhere on the system (a temp directory) triggered some rule within the AV product as something malicious. You could try specifying the target temp directory and maybe whitelist this within the product. This sort of thing has come up a few times (Sophos hates PAR::Packer!,Super Search for more). Do both systems use the same av version and definition file?
