     with standalone **CMake** tool.
 
 - [Python 3.6+](https://www.python.org/downloads/) (add to PATH)
-- [Qt 6.7.3](https://www.qt.io/download-qt-installer) In case you can't download from the official installer, you can use [Another Qt installer](https://github.com/miurahr/aqtinstall) (In that case you will need to manually add the "qtmultimedia" module when installing Qt)
+- [Qt 6.8.0](https://www.qt.io/download-qt-installer) In case you can't download from the official installer, you can use [Another Qt installer](https://github.com/miurahr/aqtinstall) (In that case you will need to manually add the "qtmultimedia" module when installing Qt)
 - [Vulkan SDK 1.3.268.0](https://vulkan.lunarg.com/sdk/home) (see "Install the SDK" [here](https://vulkan.lunarg.com/doc/sdk/latest/windows/getting_started.html)) for now future SDKs don't work. You need precisely 1.3.268.0.
 
 The `sln` solution available only on **Visual Studio** is the preferred building solution. It easily allows to build the **RPCS3** application in `Release` and `Debug` mode.
 
 In order to build **RPCS3** with the `sln` solution (with **Visual Studio**), **Qt** libs need to be detected. To detect the libs:
-- add and set the `QTDIR` environment variable, e.g. `<QtInstallFolder>\6.7.3\msvc2019_64\`
+- add and set the `QTDIR` environment variable, e.g. `<QtInstallFolder>\6.8.0\msvc2019_64\`
 - or use the [Visual Studio Qt Plugin](https://marketplace.visualstudio.com/items?itemName=TheQtCompany.QtVisualStudioTools2019)
 
   **NOTE:** If you have issues with the **Visual Studio Qt Plugin**, you may want to uninstall it and install the [Legacy Qt Plugin](https://marketplace.visualstudio.com/items?itemName=TheQtCompany.LEGACYQtVisualStudioTools2019) instead.
 
 In order to build **RPCS3** with the `CMake` solution (with both **Visual Studio** and standalone **CMake** tool):
-- add and set the `CMAKE_PREFIX_PATH` environment variable to the **Qt** libs path, e.g. `<QtInstallFolder>\6.7.3\msvc2019_64\`
+- add and set the `CMAKE_PREFIX_PATH` environment variable to the **Qt** libs path, e.g. `<QtInstallFolder>\6.8.0\msvc2019_64\`
 
 ### Linux
 
 These are the essentials tools to build RPCS3 on Linux. Some of them can be installed through your favorite package manager:
 - Clang 17+ or GCC 13+
 - [CMake 3.28.0+](https://www.cmake.org/download/)
-- [Qt 6.7.3](https://www.qt.io/download-qt-installer)
