I have a permanent licens on inventor 2020Now I have pay Autodesk for subscription for a rented Vault (software is 2020)Can these 2 programs run together without problems?best regards Ben

Yes, licensing doesn't not influence the program functionality. And Inventor 2020 is compatible with Vault 2020.Just make sure you stay on Win10 with these 6 years old versions of CAD/PDM software.
