Xarchiver successfully extracts from 7z. It fails to create a 7z archive, with the following error message:
/apps/xarchiver/local/bin/7za: line 2: ././/local/lib/p7zip/7za: not foundAll other formats create and extract OK.
Having configured Set Run Action in Rox-Filer to open a 7z archive in Xarchiver, the Xarchiver GUI opens and immediatly closes. For all other formats the Xarchiver GUI opens as expected via Set Run Action.
