Newer VMware Tools versions (11.1.x and later) bundle drivers that are signed with SHA-2. When you try to install these drivers on an unpatched Windows 7 system, the operating system's driver signature verification process fails because it doesn't recognize SHA-2 signatures. This failure triggers the "must be installed manually" error and halts the installation. kbvmware s article 78708 free
