The new Altium Designer has more features than the older versions. Certain things like polygons are done differently than they were before. That means that the libraries and PCB files are not backward compatible.
You can have someone with the new version save the libraries for you in the older format. Altium Designer has the ability to export to any of the older formats. Just be aware that you will lose some features that didn't exist in the older software.
Does anybody have libraries for TDA7293 & 7294. I searched on the AltiumDXP2004 libraries and don't found it.
No time to create by myself so, please, give some support
