This is what my version says. Almost the same.
java.security.PrivilegedActionException: java.io.IOException: Cannot run program “cmd” (in directory “C:\Program Files\Steinberg\Install Assistant”): CreateProcess error=267, The directory name is invalid
And also says error in java.security.accesscontroller.doprivileged(native method)
have the same problem today with Nuendo.
Creating that folder didn’t help.
I selected other location on other drive.
download went ok but steinberg download manager couldn’t install.
launched amnually the Nuendo_11.0.41_Installer_win.exe
but something else went wrong.
any help welcome.
