# Visual Studio Runtime VIOSO's software requires the most recent runtime libraries of Visual Studio to be present. These runtimes are usually installed when running the installer of VIOSO software. If this is blocked or interrupted, the software cannot run and exit with numerous errors like crashes, failure messages, etc. If you run in such a case, please download and (re-)install the latest Visual Studio runtime: * Download here: [Microsoft Visual C++ Redistributable packages for Visual Studio 2015, 2017, 2019, and 2022](https://aka.ms/vs/17/release/vc_redist.x64.exe) * After downloading, double-click to install and follow the instructions of the runtime installer * If required, please reboot (don't skip this!) If an error running VIOSO software persists, please also check if the [DirectX Runtime](/preparation/os/directx-runtime.md) is installed properly and if an error still persists, please contact (please tell us the Windows version and add screenshots of any error message when contacting our support). --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
