Can you provide the Altium .PcbDoc file in 5.0 binary format.
I use Circuit Studio. It can open all Altium Designer files except PcbDoc files that are saved in a newer version than binary 5.0. Because I need it only as reference design it doesn’t matter if some information gets lost.
- The file must be exported from Altium Designer as a specific binary version:
In Altium Designer, with your PCB open. File > Save Copy As, set the Save as type: to PCB 5.0 Binary File (*.PcbDoc).
