| Error Message / Symptom | Likely Cause | Solution | | :--- | :--- | :--- | | (Error 0x80070652) | A previous Windows Installer (msiexec) process is still running in the background. | Open Task Manager, go to the Details tab, and end every msiexec.exe process. Alternatively, run taskkill /im "msiexec.exe" /f as administrator in Command Prompt. | | “Incorrect function” (Error 0x80070001) | The installer is trying to run an outdated or corrupted package, often related to DirectX or Visual C++ components. | Manually download and install the latest Visual C++ Redistributable for your architecture. For 64‑bit Windows, run vc_redist.x64.exe from Microsoft’s official site, then retry the UE4 prerequisites installer. | | “Error 0x80070538 – invalid ACL” | The installer cannot write to certain system areas because of permission restrictions or a corrupted ACL (Access Control List). | Run the installer as Administrator. If the error persists, check your user account permissions or temporarily disable any aggressive antivirus software. | | Prerequisites installer requests a “network resource” that is unavailable | The installer’s internal XML manifest points to a download URL that is no longer valid, or your computer is offline when it tries to download components. | Use the offline installer method if available, or manually install the latest Microsoft Visual C++ and DirectX runtimes separately, then bypass the UE4 prerequisites step. | | The installer runs every time I launch a game | The game’s launch script incorrectly calls the prerequisites installer each time instead of checking whether components are already installed. | If you are comfortable editing configuration files, look for a file named prereq.vdf in the game folder and set the “NoCleanUp” flag to 1. Alternatively, add the /quiet flag to suppress the pop‑up window. | | The x64 version fails to install but the x86 version works | This usually indicates a conflict with a pre‑existing, corrupted 64‑bit version of a Visual C++ redistributable. | Uninstall all Microsoft Visual C++ Redistributable packages from “Add or Remove Programs,” then reinstall the latest all‑in‑one package from Microsoft before running the UE4 prerequisites again. | ue4 prerequisites x64 setup link download
