+# Windows 7 x64 compatibility build (experimental)
+
+This separate build targets **64-bit Windows 7 SP1**. It uses OpenGL instead of wgpu,
+and omits the native AccessKit accessibility adapter. Printer discovery supports the
+PowerShell version included with Windows 7, and printer setup opens Control Panel.
+The normal desktop and web builds retain their existing defaults. A vendor graphics driver providing **OpenGL 3.3 or newer**
+is required; the Windows built-in generic display driver is insufficient. GPU selection
+in Preferences and `WGPU_POWER_PREF` do not control this OpenGL build.
+
+## Build or download
+
+In your GitHub fork, open **Actions → Windows 7 x64 compatibility → Run workflow**.
+When it succeeds, download the `vectorcraft-windows7-x64-portable` artifact, extract the
+contained portable ZIP, then run `vectorcraft.exe` on Windows 7. The CLI is included.
+No MSI is provided: the existing installer remains for modern Windows.
+
+To build locally, use a **Windows 10/11 build computer**, with Rust/rustup and Visual Studio
+2022 C++ build tools (x64 compiler and Windows SDK). Open an **x64 Native Tools Command
+Prompt for VS 2022**, change to your clone's repository root (the directory containing
+`Cargo.toml`), and run:
+
+```powershell
+powershell -ExecutionPolicy Bypass -File packaging/windows/windows7.ps1
+```
+
+Output: `dist/release/vectorcraft-windows7-x64-portable.zip`. The script installs the pinned
+nightly compiler and `rust-src`, rebuilds the standard library for
+`x86_64-win7-windows-msvc`, and links the C runtime statically. It never installs Rust on
+the Windows 7 machine. The optional `CRAFT_FONTS_DIR` setting works as in the normal build.
+Without it, install fonts for the languages you need on the destination machine.
+
+The Windows 7 target matters: modern Rust's ordinary `x86_64-pc-windows-msvc` target
+requires Windows 10, including standard-library and random-number APIs. Selecting OpenGL
+alone or changing an installer version check cannot fix that.
+
+References: [Rust's Windows 7 target](https://doc.rust-lang.org/rustc/platform-support/win7-windows-msvc.html)
+and [Windows baseline change](https://blog.rust-lang.org/2024/02/26/Windows-7/).
+
+The packaging script checks x64 PE headers, the subsystem version, and known incompatible
+imports (including `GetSystemTimePreciseAsFileTime`) before creating the ZIP. This is a
+regression check, not an exhaustive audit of every Windows API.
+
+The small vendored `windows-link` patch routes `CoTaskMemFree` to its documented
+`ole32.dll` export on the Windows 7 target; the newer binding otherwise imports
+`combase.dll`, which is absent on Windows 7. Other targets keep upstream behavior.
+
+## Runtime validation
+
+A user confirmed that the portable x64 compatibility build runs on Windows 7 SP1
+with an NVIDIA graphics card. Their original build failed at startup with
+`GetSystemTimePreciseAsFileTime` missing from `kernel32.dll`; the compatibility
+build resolved that failure. The tested build was based on upstream commit
+`1f7873273b67007b0aefc63313e0d34a39f45453`. The exact GPU/driver version and completion
+of every checklist item below were not recorded, so support remains experimental.
+
+## Runtime acceptance checklist
+
+A successful build on the Windows 2022 CI runner does **not** prove Windows 7 runtime
+compatibility. Before declaring support, test on a Windows 7 SP1 x64 machine and record
+its GPU, driver version, Windows updates and any missing-DLL/entry-point error:
+
+- Start `vectorcraft.exe`; verify a visible canvas, resizing, minimize/restore and exit.
+- Draw a shape, save a `.vectorcraft` document, close and reopen it.
+- Open `examples/dusk-poster.vectorcraft`; export PNG and PDF and inspect both.
+- Exercise native Open/Save dialogs, clipboard text/images and drag-and-drop.
+- Change a preference, exit and verify it survives restarting.
+- Run `vectorcraft-cli.exe --version` and a headless export from a Command Prompt in the
+  extracted application folder.
+
+This build is experimental until that checklist passes. New dependency versions can add
+newer Windows imports, so retain Cargo.lock and repeat runtime QA after dependency updates.

+# Windows 7 x64 import compatibility
+
+Upstream: Microsoft windows-link 0.2.1, from crates.io, MIT OR Apache-2.0.
+Source: https://crates.io/crates/windows-link/0.2.1
+The original license texts are retained here.
+
+Only the non-x86 win7-target macro differs: CoTaskMemFree is imported from
+ole32.dll rather than combase.dll. windows-sys 0.61.2 otherwise causes native
+file dialogs to introduce a DLL absent on Windows 7. Ordinary targets retain
+upstream behavior. This is a binding correction, not a replacement allocator.
+
+Microsoft documents Ole32.dll and Windows 2000 as the API's minimum:
+https://learn.microsoft.com/en-us/windows/win32/api/combaseapi/nf-combaseapi-cotaskmemfree
+
+The Windows 7 packaging check rejects combase.dll to guard this fix. Remove this
+patch when upstream bindings provide the same compatibility and recheck imports.

+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.

+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You

+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or

+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+

+## Linking for Windows
+
+The [windows-link](https://crates.io/crates/windows-link) crate provides the `link` macro that simplifies linking. The `link` macro is much the same as the one provided by [windows-targets](https://crates.io/crates/windows-targets) but uses `raw-dylib` and thus does not require import lib files.
+
+* [Getting started](https://kennykerr.ca/rust-getting-started/)
+* [Samples](https://github.com/microsoft/windows-rs/tree/master/crates/samples)
+* [Releases](https://github.com/microsoft/windows-rs/releases)
+
+Start by adding the following to your Cargo.toml file:
+
+```toml
+[dependencies.windows-link]
+version = "0.2"
+```
+
+Use the `link` macro to define the external functions you wish to call:
+
+```rust
+windows_link::link!("kernel32.dll" "system" fn SetLastError(code: u32));
+windows_link::link!("kernel32.dll" "system" fn GetLastError() -> u32);
+
+unsafe {
+    SetLastError(1234);
+    assert_eq!(GetLastError(), 1234);
+}
+```
