--- Comment #2 from alexis.happyphoenix@gmail.com --- Hi, yes, it's publicly available and doesn't cost anything. I put links to the download pages in my original report, but the links here get you the actual files. Design Spark can be found here: https://pcb.designspark.info/DesignSparkPCB_v10.0.exe DS will want you to register however, and it phones home (I consider a small price for such useful software!) Library Loader can be found here: https://componentsearchengine.com/LibraryLoader.php Sufficiently old versions of Library Loader will work (I have 2.28) but you probably can't download one. Do you want a log file from that? (TBH I couldn't see a much difference up to where 2.49 fails)
