You need to use 64-bit `Visual Studio 2022 v143 toolset` as described in the [build instructions](https://slicer.readthedocs.io/en/latest/developer_guide/build_instructions/windows.html).

Thanks for uploading the log, this was helpful.

After inspecting it, the first error is related to the download of the Python sources:

It turns out that the download of any archive over https is not working … (e.g download of `swigwin-4.0.2.zip` is also failing)

Could you try the following ?

### (1) SlicerCheckCMakeHTTPS

Can you run the following command ?

```auto
cmake -P D:/S/CMake/SlicerCheckCMakeHTTPS.cmake

```

The following output is expected:

```plaintext
-- Checking if CMake supports https
-- Checking if CMake supports https - ok

```

### (2) Download of files using the web browser

Can you download the following files, locally compute their checksum and confirm they match the one reported below ?

It seems there are issues\[1\]\[2\] with newer TLS protocols.

You could try to workaround the issue by downloading these files into the top-level build directory and attempt to resume the build.

Here are the files to download into `D:\R`

Look like I incorrectly composted the URL and forgot to replace `${launcher_version}` with `0.1.31`.

In this case, you should use:

- [https://github.com/commontk/AppLauncher/releases/download/v0.1.31/CTKAppLauncher-0.1.31-win-i386.tar.gz](https://github.com/commontk/AppLauncher/releases/download/v0.1.31/CTKAppLauncher-0.1.31-win-i386.tar.gz)

## Background

For future reference, the corresponding URLs have been put together looking at the external projects (see `External_*.cmake` files in [Slicer/SuperBuild](https://github.com/Slicer/Slicer/tree/main/SuperBuild)) downloading files.

Note that `PCRE` archive is not used on Windows. This can be confirmed by inspecting the `External_PCRE.cmake` file.

```bash
cd /path/to/src/Slicer/SuperBuild

$ ack "\sURL "
External_CTKAPPLAUNCHER.cmake
43: URL https://github.com/commontk/AppLauncher/releases/download/v${launcher_version}/${CTKAppLauncherFileName}

External_CTKResEdit.cmake
37: URL ${url}

External_Swig.cmake
32: URL https://github.com/Slicer/SlicerBinaryDependencies/releases/download/swig/swigwin-${SWIG_TARGET_VERSION}.zip
98: URL https://github.com/Slicer/SlicerBinaryDependencies/releases/download/swig/swig-${SWIG_TARGET_VERSION}.tar.gz

External_PCRE.cmake
54: URL https://github.com/Slicer/SlicerBinaryDependencies/releases/download/PCRE/pcre-${_version}.tar.gz

External_OpenSSL.cmake
154: URL ${OpenSSL_${OPENSSL_DOWNLOAD_VERSION}_URL}
307: URL ${OpenSSL_${OPENSSL_DOWNLOAD_VERSION}_${MSVC_VERSION}_URL}

External_tbb.cmake
42: URL https://github.com/oneapi-src/oneTBB/releases/download/v${tbb_ver}/${tbb_file}

External_python.cmake
66: URL ${_download_${Slicer_REQUIRED_PYTHON_VERSION}_url}

```

Dear Jcfr:  
I still got problems when doing the ‘ALL\_BUILD’, this time it stuck in ‘cloning to VTK…’ ,can you please check the log file, maybe I should download more packages before hand?
