I have got the vxdiag vcx nano toyota techstream 16.20.023 and driver installed. But unable to connect vcx nano with techstream software.
Error Unable to connect to VIM
If have installed passthru and Toyota driver in VX Manager, delete vx manager and reinstall again.
Update license and firmware.
Then VXDIAG Toyota will be shown in VIM Selection.
Yes, uninstall and reinstall vx manager, it is now connected.
