- "This app can't run on your device" — Corrupted download or incompatible bitness. Re-download from the official site and confirm the correct version.
- Start Menu shortcut missing — The installer did not complete fully. Re-run the
.exeand choose Repair or uninstall first before reinstalling. - Antivirus flags the installer — Some antivirus suites quarantine the installer. Add an exclusion for LM Studio in the antivirus settings during installation.
