+  If you don't have the game installed (or own a cracked/pirated copy of it) you can download it for free from the official **Battle.Net** servers using [Battle.Net Installer](https://github.com/barncastle/Battle.Net-Installer) and executing this command:
+  
+   ```
+   .\bnetinstaller.exe --prod lazr --uid lazarus --lang enUS --dir "YOUR INSTALL PATH"
+   ```

+   **Make sure to replace "YOUR INSTALL PATH" with an actual installation path of your choice.**
+3. Run **h2-mod.exe** and make sure you press **"YES"** when asked whether to install updates.

+- If you get crashes that show errors like **"Create2DTexture(...) failed ..."** or **"IDXGISwapChain::Present failed: ..."** when loading certain maps try:
+  * Disabling shader preloading
+  * Lowering graphics settings
+  * Freeing up RAM (close programs)
+  * Updating your GPU drivers
