I have the same problem under Win7 pro 32 bits, since I've updated to the lastest version (v2.15.578). Boxcryptor doesn't start without error message. When I try to launch Boxcryptor using bc.cmd, I have a message "Boxcryptor stop working".
In the event viewer I have this :
"Failed to open pipe "\\.\pipe\Boxcryptor_App_RVpWT1NUUk8xNzIwXEVsaXNhYmV0aA==" in src\pipe\PipeClient.cpp LastError: Le fichier spécifié est introuvable."
Can someone help me ? I'm stuck and cannot work anymore.
