Problem with Version 4.3.27


I have a problem with the last version (4.3.27).

I’m trying to open projects created with Pix4d 4.1.25 but in the new version they are not aligned with the GCPs…Does anybody know why I have this problem?

Is there a way to avoid processing again Step 2 and 3??

Thank you so much

I have that same problem. this is the chronic issue after Pix4d version update.

Can we rollback the update? we are having the same issue while in the middle of a project that needs to go out ASAP. 

Yes, you can. 

  1. Go to our website here.
  2. Click on the Windows/Linux icon.
  3. The version 4.2.27 will start to download.

The thing is all the proyects that were open in the newest version (altough i didn’t upgrade the version of the software to the proyect)  can’t be opened in the 4.3.27 version. It keeps on oping up the error e0400C.

Should we use notepad++ to modify something? Wich line?

Unfortunately, this time it seems to be not enough to just change a p4dversion in the p4d file. 

Our developers are currently reviewing the affected projects to find a solution or a workaround. 

I’ll keep you posted here once I get more updates.


Hi all!
