Quick summary

Imagen couldn't create or open the folder it needs to save your edits, so the download couldn't start.

How to fix this

1. Make sure the drive where your photos or catalog are stored is connected. External and network drives are the most common cause.
2. Check that the folder isn't read-only and that you're allowed to save files there.
3. Avoid cloud-synced folders (Dropbox, iCloud, OneDrive, Google Drive). Move the files to a local folder if you can.
4. Mac: Give Imagen access to your folders. Go to Apple menu › System Settings › Privacy & Security › Files and Folders, find ImagenAI, and turn on the folders. Then go to Full Disk Access, and turn on ImagenAI.
5. Windows: If Controlled folder access is on, Windows blocks apps from changing files in protected folders like Pictures, Documents and Desktop. Go to Windows Security › Virus & threat protection › Manage ransomware protection, select Allow an app through Controlled folder access, and add Imagen.
6. Make sure there's at least 1 GB of free disk space, restart Imagen, and download again.
