Troubleshooting

Install issues

These come up regularly — usually solvable in 30 seconds.

Windows shows "Windows protected your PC" and refuses to run the installer⌄
This is SmartScreen protecting against installers without an Extended Validation code-signing certificate. Click "More info" → "Run anyway". Once enough installs accumulate reputation, the warning disappears.
macOS says "cannot verify the developer"⌄
System Settings → Privacy & Security → scroll to the bottom and click "Open Anyway". Or in Terminal: `xattr -dr com.apple.quarantine /Applications/Rethink\ Data.app`
Does Apple Silicon (M1/M2/M3) work natively?⌄
Yes, the macOS DMG is a universal binary supporting both Intel and Apple Silicon. The OS picks the right architecture automatically.
The download link is slow or blocked⌄
Make sure your network can reach quantdatafetch.com. Some corporate / campus networks block .exe / .dmg downloads — try a different network (home Wi-Fi, mobile hotspot) if so.
App installs but crashes on launch⌄
Send the client logs to support. Windows logs live in `%APPDATA%/Quant Data Fetch/logs/`, macOS in `~/Library/Application Support/Quant Data Fetch/logs/`. Include your OS version and the last few lines of any error log.
