Damaged Ledger Wallet Download File | Official Entry, File Check, and Retry Note: practical reference notes for this topic (scope-specific to id=199068).
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. (id=199068 scope-specific note for "Damaged Ledger Wallet Download")

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. (id=199068 scope-specific note for "Damaged Ledger Wallet Download")
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. (id=199068 scope-specific note for "Damaged Ledger Wallet Download")
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. (id=199068 scope-specific note for "Damaged Ledger Wallet Download")
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. (id=199068 scope-specific note for "Damaged Ledger Wallet Download")
The retry note should not include PIN digits or recovery phrase words. It only needs to preserve the file state and the visible result. (id=199068 scope-specific note for "Damaged Ledger Wallet Download")
