So when i ThinApp Skype, i set WriteCopy isolation mode for the entire capture. Then before the build process in the build directory there is no %dirve_c%. I manually create the virtual drive with NO ##Attributes.ini. Normally it will inherit the isolation mode from the package.ini file which is set to WriteCopy. It doesn`t work. Then i am creating a ##Attributes.ini with DirectoryIsoloationMode=WriteCopy, and rebuilding the project. Stil the sam thing.
