Isaac 6.0 installation issue

[jackykortrijk]

Hi, there! There is an error occurring during the installation. After I executed the "build.bat" under the isaacsim folder, an error happened as follows. Can someone tell me how to fix this error? Btw, I have already installed the C++ MSVC and SDK, but not installed under the BuildTools folder, since it is Visual Studio 2022 community and BuildTools folder is not created. Thank you very much!

The build is failing because it’s looking for the MSVC toolchain under Build Tools (...\2022\BuildTools\), but the file VC\Auxiliary\Build\Microsoft.VCToolsVersion.default.txt is missing there. That usually means either the build picked a Build Tools path by mistake, or you only have Visual Studio 2022 Community (which installs under a Community folder, not BuildTools).

Fix: point the build at your Community install

In your repo root, edit repo.toml and set the Visual Studio path explicitly. Under the [repo_build.msbuild] section, add or uncomment vs_path and set it to your Community installation. For a default install:

[repo_build.msbuild]
link_host_toolchain = true
vs_version = "vs2022"
vs_path = "C:\\Program Files\\Microsoft Visual Studio\\2022\\Community\\"

Use double backslashes in the path. If your Community install is in a different location, set vs_path to that path (with a trailing backslash). Then run build.bat again.

More detail

The Windows C++ Developer Configuration doc describes this: it recommends Visual Studio 2022 Community and shows how to set vs_path when the build doesn’t pick the right install. The “Configuring an Existing Installation” and “Non-Default Installation Paths” sections are the relevant parts.

Thank you for your answer. The problem has been solved!

I had the same issue when trying to install the Isaac Sim 6.0 dev2 release. For building from source, it would be great if VS Community Edition could be automatically detected by the script.
