How to configure Issac Sim with Visual Studio 2026?

[6157894t53484-dot]

I can not find Visual Studio 2022 installation so I install 2026 version,but when I write the configuration in the repo.toml as follow:

[repo_build.msbuild]
sln_file = "isaac-sim.sln"
# If set to true will attempt to link to host's Visual Studio and Windows SDK installations.
# This is needed if C++ compilation is needed on Windows, and repo_build.build.enabled is set to true.
link_host_toolchain = true   # This requires Microsoft Visual Studio BuildTools installed.

# Filter on Visual Studio version e.g.: Visual Studio 2022. Empty string will match all years and prioritize the newest.
vs_version = "vs2026"


# Visual Studio path; This will be used if the user would like to point to a specific VS installation rather than rely on heuristic locating.
vs_path = "D:\\Microsoft Visual Studio\\18\\Community\\"

"token:in_ci==false".version_check_vs_version = "2026"
"token:in_ci==false".version_check_msvc_version = "v145"
"token:in_ci==false".version_check_msbuild_version = "17"
"token:in_ci==false".version_check_winsdk_version = "10.0.26100.0"

# Filter specifically to "Enterprise", "Professional", or "Community" editions of Visual Studio
vs_edition = "Community"

# Filter by Visual Studio installations that have installed this version of the MSVC compiler.
msvc_version = "v145"

# Filter by Visual Studio installations that ship with MSBuild of this major version.
msbuild_version = "17"

# Windows SDK version
winsdk_version = "10.0.26100.0"

# Windows SDK path; This will prevent needing to dynamically locate an installation by guesswork.
winsdk_path = "D:\\Windows Kits\\10\\bin\\10.0.26100.0"

And then run

build.bat

The terminal said that:

Use the Visual Studio installer to add version: v145 or change your repo.toml.

I would be really appreciate it if someone can lend me a hand!

Hi @6157894t53484-dot,

Visual Studio 2026 is supported for building Isaac Sim -- you just need to install the required MSVC toolset and fix your repo.toml configuration.

Problem

The error message tells you exactly what's wrong:

Visual Studio installation at D:\Microsoft Visual Studio\18\Community does not contain a matching version of the Visual Studio Build Tools. Use the Visual Studio installer to add version: v145

Your VS 2026 installation is missing the MSVC v145 C++ compiler toolset.

Fix: Install MSVC v145

1. Open Visual Studio Installer
2. Click Modify on your VS 2026 Community installation
3. Go to Individual components tab
4. Search for and select: MSVC v145 - VS 2026 C++ x64/x86 build tools
5. Also ensure Windows 11 SDK (10.0.26100.0) is selected
6. Click Modify to install

Alternatively, re-run the recommended install command which includes these components:

winget install --id=Microsoft.VisualStudio.Community -e --override "--add Microsoft.VisualStudio.Workload.NativeDesktop --includeRecommended"

Fix: Correct Your repo.toml

Your configuration has some issues:

# [x] Your current config
vs_version = "vs2026"           # Wrong format
msbuild_version = "17"          # Wrong for VS 2026

# [v] Correct config for VS 2026
vs_version = "18"               # VS 2026 = version 18
msvc_version = "v145"           # Correct
msbuild_version = "18"          # VS 2026 uses MSBuild 18
winsdk_version = "10.0.26100.0" # Correct

Here's the corrected [repo_build.msbuild] section:

[repo_build.msbuild]
sln_file = "isaac-sim.sln"
link_host_toolchain = true

vs_version = "18"
vs_path = "D:\\Microsoft Visual Studio\\18\\Community\\"
vs_edition = "Community"

msvc_version = "v145"
msbuild_version = "18"

winsdk_version = "10.0.26100.0"
winsdk_path = "D:\\Windows Kits\\10\\bin\\10.0.26100.0"

"token:in_ci==false".version_check_vs_version = "2026"
"token:in_ci==false".version_check_msvc_version = "v145"
"token:in_ci==false".version_check_msbuild_version = "18"
"token:in_ci==false".version_check_winsdk_version = "10.0.26100.0"

Quick Workaround

If you want to test the build immediately after installing MSVC v145, you can skip strict version checking:

build.bat --skip-compiler-version-check

Reference

See the Windows Developer Configuration docs for the full setup guide.

Let us know if you still have issues after installing MSVC v145!
