When a Ledger Wallet download reports a damaged file, do not continue from a half-finished installer. Return to the source entry, check the file state, and record whether the same prompt appears after a clean retry.
Direct Answer: Restart From the Source Entry
The first useful step is to return to the known Ledger app entry and avoid mixing old files with a new attempt. Use Ledger Wallet download and installation guide as the stable entry reference.
Separate File Damage From Device State
A damaged-file prompt is a computer-side file state, not a device-screen conclusion. Keep the device unchanged until the installer file can be opened cleanly and the app window is available.
Compare the Installer Path and File Check
If the file opens but the installer path or system prompt is unclear, compare the situation with Ledger Wallet desktop first install. This keeps file state, app launch, and screen prompt in separate checks.
Write a Retry Note Before Continuing
Record the entry used, file name, prompt wording, and whether a new download changed the result. If compatibility is part of the issue, add supported OS versions and Ledger Wallet compatibility to the review.
The retry note should not include PIN digits or recovery phrase words. It only needs to preserve the file state and the visible result.
