Installed IGO Primo 2.4-9.13. Works very well, thanks!
Voice folder had no Norwegian files. Found no voice files for 2.4 so far. Copied the Norwegian voice files from IGO Primo 2.0 and pasted into the 2.4 voice folder. It is Voice_Nor_m2-lua.zip and Voice_Nor-f31-lua.zip.
Whens starting Navi, I have some progress. Then message pops up - not supported voice file. Clicking OK, and startup continues, and Primo starts. Choose Norwegian voice and it works very well.
So my problem seems only to get rid of the error message.
Any suggestions?
