Quick Start (CLI)

Download

# Latest versions
msvc-kit download

# Specify versions / dirs / arch
# MSVC version can be short (14.44) or full (14.44.34823)
msvc-kit download \
  --msvc-version 14.44 \
  --sdk-version 10.0.26100.0 \
  --target C:\msvc-kit \
  --arch x64 \
  --host-arch x64

# Download only MSVC (skip SDK)
msvc-kit download --no-sdk

# Download only SDK (skip MSVC)
msvc-kit download --no-msvc

# Control parallel downloads (default: 4)
msvc-kit download --parallel-downloads 8

# Skip hash verification
msvc-kit download --no-verify

> Note: MSVC version can be specified as short format (e.g., 14.44) which auto-resolves to the latest build, or full format (e.g., 14.44.34823) for a specific build.

Windows SDK extraction notes

Windows SDK payloads contain MSI installers plus adjacent CAB source media. Keep the download cache intact while extraction runs; deleting individual CAB files can make Windows Installer fail with 1619.

Some optional SDK MSI packages, such as Application Verifier and WinRT Intellisense, are not required for MSVC/Rust toolchains and may fail administrative extraction with 1603 on long or constrained paths. msvc-kit skips those optional MSI packages and keeps extracting the SDK headers, libraries, tools, and redistributables needed for compilation.

If SDK extraction still fails:

Prefer a short target directory, for example msvc-kit download --target C:\msvc-kit.
Clear the SDK cache and retry if the error mentions missing source media: msvc-kit clean --all --cache.
Wait for Windows Update or another installer if the error is 1618.
Set RUST_LOG=debug when reporting an issue so the failing MSI, target directory, and extraction plan are visible.

Developer guidance:

Treat SDK CAB files as MSI source media, not standalone archives to unpack.
Keep non-essential SDK MSI packages opt-out/skippable unless they are needed by a verified compiler workflow.
Use short or normalized paths for msiexec whenever possible, and keep tests for known-problem package names so manifest changes do not reintroduce the regression.

Setup Environment

# Generate script for current shell
msvc-kit setup --script --shell powershell | Invoke-Expression

# Or for CMD
msvc-kit setup --script --shell cmd &gt; setup.bat &amp;&amp; setup.bat

# Portable script (rewrites install root to %~dp0runtime)
msvc-kit setup --script --shell cmd --portable-root "%~dp0runtime" &gt; setup.bat

# Or for Bash/WSL
eval "$(msvc-kit setup --script --shell bash)"

# Persist to Windows registry (requires admin)
msvc-kit setup --persistent

Create Portable Bundle

Create a self-contained bundle with MSVC toolchain that can be used anywhere:

# Create bundle (requires accepting Microsoft license)
msvc-kit bundle --accept-license

# Specify output directory and architecture
msvc-kit bundle --accept-license --output ./my-msvc-bundle --arch x64

# Cross-compilation bundle (x64 host targeting ARM64)
msvc-kit bundle --accept-license --host-arch x64 --arch arm64

# Also create a zip archive
msvc-kit bundle --accept-license --zip

# Specify versions
msvc-kit bundle --accept-license --msvc-version 14.44 --sdk-version 10.0.26100.0

The bundle contains:

msvc-kit.exe - CLI tool
VC/Tools/MSVC/{version}/ - MSVC compiler and tools
Windows Kits/10/ - Windows SDK
setup.bat - CMD activation script
setup.ps1 - PowerShell activation script
setup.sh - Bash/WSL activation script
README.txt - Usage instructions

Usage:

# Extract and run setup script
cd msvc-bundle
setup.bat          # CMD
.\setup.ps1        # PowerShell
source setup.sh    # Bash/WSL

# Now cl, link, nmake are available
cl /nologo test.c

List Versions

msvc-kit list              # Show installed versions
msvc-kit list --available  # Show available versions from Microsoft

Clean Up

msvc-kit clean --msvc-version 14.44   # Remove specific MSVC version
msvc-kit clean --sdk-version 10.0.26100.0  # Remove specific SDK version
msvc-kit clean --all                  # Remove all installed versions
msvc-kit clean --all --cache          # Also clear download cache

Configuration

Config file: %LOCALAPPDATA%\loonghao\msvc-kit\config\config.toml

msvc-kit config                        # Show current config
msvc-kit config --set-dir C:\msvc-kit  # Set install directory
msvc-kit config --set-msvc 14.44       # Set default MSVC version
msvc-kit config --set-sdk 10.0.26100.0 # Set default SDK version
msvc-kit config --reset                # Reset to defaults

Print Environment Variables

msvc-kit env                  # Print as shell script
msvc-kit env --format json    # Print as JSON

Self-Update

# Check for updates without installing
msvc-kit update --check

# Update to the latest version
msvc-kit update

# Update to a specific version
msvc-kit update --version 0.2.5

The self-update feature is powered by axoupdater and queries GitHub Releases directly. It is compatible with both cargo-dist and custom release workflows. During installation, msvc-kit pins the update to the current install root and verifies that the updated executable reports the expected version before declaring success. The self-update feature is enabled by default and can be disabled with --no-default-features at build time.

Install MSVC into Visual Studio (UBT Discovery)

Unreal Build Tool (UBT) discovers MSVC toolchains by scanning Visual Studio's installation directory. When msvc-kit downloads a toolchain to a custom location (e.g. C:\msvc-kit\14.36), UBT cannot find it. The install-into-vs subcommand copies the toolchain files into VS's toolchain directory, making them visible to UBT.

# Check VS instances and their registered MSVC versions
msvc-kit install-into-vs --check

# Install a specific downloaded toolchain into VS
msvc-kit install-into-vs --dir C:\msvc-kit\14.36

# Auto-detect and install the latest downloaded toolchain
msvc-kit install-into-vs --auto

> ⚠️ This command usually requires administrator privileges because it writes > to C:\Program Files (x86)\Microsoft Visual Studio\....

UE 5.2 + MSVC 14.36 CI Integration Example:

When building Unreal Engine plugins via GitHub Actions self-hosted runners, msvc-kit can provision the exact MSVC version required by the engine:

- name: Ensure MSVC 14.36 toolchain
  shell: pwsh
  run: |
    $msvcKitExe = "C:\msvc-kit\bin\msvc-kit.exe"
    $msvcTargetDir = "C:\msvc-kit\14.36"

    # Download if not cached
    if (-not (Test-Path "$msvcTargetDir\VC\Tools\MSVC")) {
      &amp; $msvcKitExe download --msvc-version 14.36 --no-sdk --dir $msvcTargetDir --arch x64
    }

    # Activate toolchain for this job
    $envScript = &amp; $msvcKitExe setup --script --shell powershell --dir $msvcTargetDir
    if ($LASTEXITCODE -ne 0) { throw "msvc-kit setup failed" }
    Invoke-Expression ($envScript -join "`n")

    # Install into VS for UBT discovery (requires admin)
    &amp; $msvcKitExe install-into-vs --dir $msvcTargetDir

Caching & Progress

Cache Type	Location	Description
Download index	`downloads/{msvc\|sdk}/.../index.db`	redb database for tracking download status
Manifest cache	`cache/manifests/`	Cached VS manifests with ETag/Last-Modified
Extraction markers	`.msvc-kit-extracted/`	Skip already-extracted packages

Progress display: Single-line spinner by default. Set MSVC_KIT_INNER_PROGRESS=1 for detailed file progress.
Skip logic: Downloads are skipped when:
- cached: File exists in index with matching hash
- 304: Server returns Not Modified (ETag/Last-Modified match)
- size match: File size matches expected (best-effort, noted in code)

TLS Backend Configuration

By default, msvc-kit uses native-tls (SChannel on Windows) to avoid requiring cmake and NASM during compilation. This resolves the aws-lc-sys build issue.

Feature	TLS Backend	Build Requirements	Default
`native-tls`	Platform native (SChannel/OpenSSL)	None	✓
`rustls-tls`	rustls + aws-lc-rs	cmake, NASM	-

# Default: native-tls (recommended, no extra build deps)
[dependencies]
msvc-kit = "0.2"

# Or explicitly choose a TLS backend:
msvc-kit = { version = "0.2", default-features = false, features = ["native-tls"] }

# Use rustls instead (requires cmake + NASM on Windows):
msvc-kit = { version = "0.2", default-features = false, features = ["rustls-tls"] }

Library Usage

[dependencies]
msvc-kit = "0.2"

use msvc_kit::{
    download_msvc, download_sdk, extract_and_finalize_msvc, extract_and_finalize_sdk,
    setup_environment, DownloadOptions,
};
use msvc_kit::{list_available_versions, Architecture};

#[tokio::main]
async fn main() -&gt; msvc_kit::Result&lt;()&gt; {
    // List available versions from Microsoft
    let versions = list_available_versions().await?;
    println!("Latest MSVC: {:?}", versions.latest_msvc);
    println!("Latest SDK: {:?}", versions.latest_sdk);

    // Download with builder pattern
    let options = DownloadOptions::builder()
        .target_dir("C:/msvc-kit")
        .arch(Architecture::X64)
        .build();

    let mut msvc = download_msvc(&amp;options).await?;
    let sdk = download_sdk(&amp;options).await?;
    extract_and_finalize_msvc(&amp;mut msvc).await?;
    extract_and_finalize_sdk(&amp;sdk).await?;
    let env = setup_environment(&amp;msvc, Some(&amp;sdk))?;

    println!("cl.exe: {:?}", env.cl_exe_path());
    Ok(())
}
