Troubleshooting
Short answers to keep you moving.
Can’t find Atom after installing?
- Restart After Effects, then check Window → Extensions → Atom.
- Reinstall the
.zxpwith ZXP Installer if it’s still missing. - Make sure you’re on After Effects CC 2022 (v22.0) or newer.
Manual ZXP installation
If ZXP Installer isn’t working, you can install Atom manually:
- Rename the
.zxpfile to.zipand unzip it to get the extension folder. - Copy the folder to the extensions directory:
/Library/Application Support/Adobe/CEP/extensions/ - Restart After Effects and check Window → Extensions → Atom.
Sign-in or licence hiccups
- No sign-in email? Check spam, wait a minute, then resend or try another inbox.
- Seat limit hit? Open Settings → Account → Deactivate device, then tap Refresh access.
OpenAI sign-in issues
- Browser did not open: Click Sign in with OpenAI again, or copy the link if Atom shows one.
- Signed in but Atom still asks: Return to the panel and tap Refresh.
- Wrong account: Sign out in Atom settings or your local Codex setup, then sign in with the OpenAI account you want to use.
- Team-managed setup: Confirm Codex or Claude Code works outside Atom, then restart After Effects. See Team & Custom AI Setup.
Anthropic issues
- Anthropic not detected: Restart After Effects and tap Refresh in Atom. Verify Claude Code works by running
claude --versionin a terminal. - Anthropic authentication error: Run
claudein your terminal and complete the sign-in flow. - Non-standard install path: Make sure the Claude Code binary is on your system PATH so Atom can find it.
Automations not landing
- Read the response cards. Atom explains what it found or why it stopped.
- Tighten the scope: name the comp, the layers, or say “selected layers only”.
- Undo, adjust the wording, and rerun in the same chat to build on context.
Feeling slow or stuck
- Big comps and expression scans take a moment. Let Atom finish before stacking prompts.
- Focus your request to speed things up and keep results tidy.
- If requests fail, check that you are signed in and your AI provider account has available credits or an active plan.
File attachment issues
- Unsupported file type: Atom supports images, PDFs, documents (Word, Excel, PowerPoint), text files, and audio (WAV, MP3). Video is not currently supported.
- File too large: Images max out at 5MB, audio/PDFs/documents at 10MB, text files at 1MB. Compress or trim before attaching.
- Attachment not processing: Try a different format. Some exotic image formats may not work. Convert to PNG or JPEG.
