## Installing
Download the [latest release](https://github.com/k153636/NexStrap/releases/latest) and run `NexStrap.exe`.
You will need [.NET 9 Desktop Runtime](https://dotnet.microsoft.com/en-us/download/dotnet/9.0). If it's not installed, Windows will prompt you automatically.
> Windows SmartScreen may show a warning on first launch. Click **More info** → **Run anyway**. This happens because NexStrap is not yet code-signed.

## FAQ
**Q: Is this malware?**
A: No. NexStrap is fully open source — the complete source code is available here on GitHub for anyone to verify.
**Q: Will I get banned from Roblox?**
A: No. NexStrap does not interact with the Roblox client the way exploits do. It only manages launch settings, Fast Flags, and Discord Rich Presence.
**Q: Windows Defender flagged it**
A: This is a false positive common with unsigned applications. You can review the full source code here to verify it is safe.
**Q: Does it work with multiple Roblox instances?**
A: Yes. NexStrap tracks each instance independently and shows the focused window's game in your Discord status.
**Q: Does it work with Roblox Studio?**
A: Yes. NexStrap can install and launch Studio independently, with full Discord presence support.
