Sjunior3d Do you see a red colored message that web_nothreads_debug.zip and web_nothreads_release.zip are missing in the export window as shown below?

If so, please rename web_debug.zip and web_release.zip in the export template folder toweb_nothreads_debug.zip and web_nothreads_release.zip, respectively. You can open the folder via the Open Folder button on the export template manager window:

This should result in a successful export. If it still doesn't work, please let us know.
