I installed Adapt Learning locally (http://localhost:5000/) and I created a sample course. I can see the preview, but when I click the button "Download" the following message appears: "Cannot GET /download/58f118261a4f1e7441c3204b/58f1c27bac8224f0055c529f//download.zip". Any suggestions?
Answer for those who will face the same problem:
1. Check symbols in "Title" in "Project settings". Most likely, only english letters and west arabic numbers are suitable.
I changed title from cyrillic to english letters and it worked.
"Display Title" can be in your language.
2. Also you can find .zip in the folder having path adapt_authoring\temp\хххххххххххххххххххх\adapt_framework\courses\хххххххххххххххххххх\хххххххххххххххххххх (last one is id course same as in path http://localhost:5000/#editor/хххххххххххххххххххх )
