Possible to Download VXDIAG Firmware to V1.6?

Question:

Hi is there a way to downgrade my vxdiag vcx se version to 1.6 and back to new version without loosing my license or hardware?

Answer:

No, it is not possible once you update you can't go back.
VX Manager FW1.8+ has a different license. You will lose all licenses after downgrading.
You can downgrade with loosing licenses.
After return back to the FW1.8+ licenses restored from the VXdiag server.
Newly installed licenses completely overwrite old.

Actually licenses for the VXDiag SE FW1.6 should be the same as VXDiag nano.
Better don't downgrade firmware.
