The reason it flicks up then exits is you're meant to use it in command prompt by cd'ing to the directory its in then do something for example ungpkg PACKAGE.PKG packageUnpack (last word = folder you want it in, needs to already be created).
so ur saying open cmd n type were the package_finalize.exe is n then wen it opens it type the name of the .pkg im trying to extract?
