+> **If RemSound won't start** — if Windows says it needs “.NET” — RemSound runs on the **Microsoft .NET 10 Desktop Runtime**. Most up-to-date Windows machines already have it; if yours doesn't, open the **Install Scripts** folder sitting next to `RemSound.exe` and double-click **Install .NET for RemSound.cmd**. It fetches and installs it for you (using winget, the Windows package manager), and then RemSound will start. There's a `.ps1` version in the same folder for PowerShell users. If you'd rather do it by hand, the script opens Microsoft's download page, where you pick “.NET Desktop Runtime” for “x64”.

Let's assume you and a friend both have RemSound running, and that your two computers can reach each other on the network (the same Wi-Fi, the same Tailscale account, and so on).
1. Start RemSound. The first thing you'll see is the **profile picker**. On a brand-new install your only choice is **New profile** — select it and press Enter or click OK. Later, once you've saved a setup or two of your own, this is the dialog where you choose which one to load. See Profiles for the full story.
