Answer
Download VALORANT only from Riot. Before retrying, note the exact installer message, check Riot's status, free disk space, Windows updates, and the connection. Restart the Riot Client, run its repair tool for a partial installation, and restart Windows when Vanguard asks. Reinstall Vanguard or VALORANT only after the smaller checks fail.

Check status, storage, and Windows
Check Riot's service status, make enough free space for the download and installation, and install pending Windows updates.
Close Riot Client completely, restart Windows, and retry on a stable connection. Pause other large downloads and disconnect a VPN or proxy for this test.

Repair a partial installation
If VALORANT appears in Riot Client but will not finish or launch, open its Settings and use Repair.
If Riot installs or updates Vanguard, restart Windows before judging the result. Follow any displayed VAN code instead of guessing.
7
Reinstall only the broken part
If the exact error points to Vanguard, use Riot's removal instructions and let VALORANT reinstall it. Reinstall the full game only if repair and the smaller checks fail.
