No Rust installation detected. You can download official Rust installer

[stiv-yakovenko]

I've installed visual rust 0.1.2, I have rustc.exe and some other files installed here: C:\Users\steve.cargo\bin
But when I try to build rust project in msvc 2015 I get this error:

C:\Program Files (x86)\MSBuild\VisualRust\VisualRust.Rust.targets(53,5): error : No Rust installation detected. You can download official Rust installer from https://www.rust-lang.org/downloads.html

How is the installation detected? How can I fix this?

Here is where installation paths that get checked are enumerated:

VisualRust/src/VisualRust.Shared/Environment.cs

Lines 84 to 102 in f005c24

	public static IEnumerable<string> GetAllInstallPaths()
	{
	if (System.Environment.Is64BitOperatingSystem)
	{
	return GetInstallRoots(RegistryHive.CurrentUser, RegistryView.Registry64)
	.Union(GetInstallRoots(RegistryHive.CurrentUser, RegistryView.Registry32))
	.Union(new string[] { GetMultirustInstallRoot(), GetRustupInstallRoot() })
	.Union(GetInstallRoots(RegistryHive.LocalMachine, RegistryView.Registry64))
	.Union(GetInstallRoots(RegistryHive.LocalMachine, RegistryView.Registry32))
	.Union(GetInnoInstallRoot());
	}
	else
	{
	return GetInstallRoots(RegistryHive.CurrentUser, RegistryView.Registry32)
	.Union(new string[] { GetMultirustInstallRoot(), GetRustupInstallRoot() })
	.Union(GetInstallRoots(RegistryHive.LocalMachine, RegistryView.Registry32))
	.Union(GetInnoInstallRoot());
	}
	}

VisualRust/src/VisualRust.Shared/Environment.cs

Lines 115 to 125 in f005c24

	static string GetRustupInstallRoot()
	{
	// rustup.rs installs into %CARGO_HOME%\bin\ and %CARGO_HOME% defaults to %USERPROFILE%\.cargo\
	string cargoHome = System.Environment.GetEnvironmentVariable("CARGO_HOME");
	if (String.IsNullOrEmpty(cargoHome))
	{
	string userprofile = System.Environment.GetFolderPath(System.Environment.SpecialFolder.UserProfile);
	return Path.Combine(userprofile, ".cargo");
	}
	return cargoHome;
	}

Might just need to set CARGO_HOME appropriately.

Same for me with rust 1.20 on Windows 10 64bit Visual Studio 2015.

I have set CARGO_HOME to C:\Users\dzmitry_lahoda\.cargo, but still have and issues.

[MaulingMonkey]

Ahh, sorry, I've just noticed that the logic is different in Visual Rust 1.2.0 - it doesn't support CARGO_HOME: https://github.com/PistonDevelopers/VisualRust/blob/0.1.2/VisualRust.Shared/Environment.cs

Setting MULTIRUST_HOME to your .cargo path might work, or there are some earlier workarounds with registry keys: #263 . Alternatively, grab the trunk version from https://ci.appveyor.com/project/vosen/visualrust/build/artifacts (or follow the Readme's appveyor links).

I have installed VS 2017 Pro and latest plugin. No install errors, but no templates in New Project.

[dzmitry-lahoda]

MULTIRUST_HOME seems deprecated.

[MaulingMonkey]

There's an unmerged pull request to fix the templates and other issues: #286

[lucabtz]

Any news on this Issue, I'm having the same problem, even after setting the CARGO_HOME
Need any help fixing this?

Solution from this bug helped me.
Solution. Create file rust-win.reg with similar content (replace TODO_Place_your_username_here to your actual path.

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Mozilla Foundation\Rust\1.66.0]
"InstallDir"="C:\\Users\\TODO_Place_your_username_here\\.cargo\\"

Then run it by double-clicking on the file.
