My antivirus won’t allow installation
- Disable your antivirus temporarily (only for installation) and re-enable it afterward.
- If a warning pops up, click "More info" > "Run anyway".
- Your antivirus may scan the file first—let it finish before launching.
Does this launcher include OptiFine?
No, but you can install it manually:
- Download the correct version from the official OptiFine website.
- Open the file and click Install—it will create a new profile in the launcher.
- For Minecraft 1.16+, we recommend Iris + Sodium for better performance (with mods like Zoom for OptiFine-like features).
VirusTotal/Your antivirus flags Titan Launcher as a virus!
VirusTotal scans Titan Launcher with multiple antivirus tools. However, well-known antiviruses like Microsoft Defender, Kaspersky, and others do not flag it as a threat! Only a small number of unreliable antiviruses mistakenly flag Titan Launcher, often marking any less common apps as malicious, not just Titan Launcher.
To stay safe, always download Titan Launcher directly from our official site, and avoid third-party websites!
