Problem opening old file with KiCAD 5.1.0

When I launch PCB Layout editor of an old version of KiCAD I get this error but I do not understand what do I do :roll_eyes:

Could you post the whole project or at least the board file here?

Your thread subject says “latest” and then your post says “old”
Which version do you mean?

I interpreted it meaning that the project is created with an old version.
EDIT: the error message point to that. The layer names have been in another language than English in some old versions, IIRC.

So I suspect we need an import workaround.

Please have a look at the instructions here:

sorry for my english…
I created the file with 2013-07-07 version and when I open it with 5.1.0 version I get this alert…
the same problem is also present on other projects…
The file I can not upload it because I am a new user… but I shared here: diginterface V3.kicad_pcb

Seth gave the instructions above, read it.

Edited thread title.
There was a bug opening V3 projects, but there was a fix. This needs to be raised as a new bug. KiCad should always be able to import old versions

Hello. The solution for this problem is here :

It’s a Perl script to convert from the old PCB format.

This appears to be a V3 to V5 import, so not applicable

The pcb format did not really change from v4 to v5. This means the same process to get a pcb file from version 2013 to version 4 will still work to get the same file to version 5 directly.

I don’t understand I’m really confused… some projects work regularly, others do not: and they have all been done with the same version of KiCad

For some reason someone back then thought it is a good idea to translate layer names inside the file format. I would assume this was tied to the language of kicad itself. Meaning it is not only dependent on the kicad version that was used to create the file but possibly also the language selected for it while creating the file.

but I had the same problem with V4: I installed V5 thinking to solve…
v3 to v4 the same problem
v3 to v5 the same problem

That is what i was meaning with the post you answered to. KiCad 5 and KiCad 4 need the same process to open a v3 project (created in a different language than english).

Did you try the process described by the answer of @Seth_h?

For me work, see picture

Did this make problems when a KiCad 3 Polish file was read by a KiCad 3 Spanish PC?
What a bizarre thing to do.

ok… having the projects in my old PC with the old version of KiCAD : I could set the old KiCAD in English language and save again and solve?

argghhhhhh more confused! yes it’s ok!
