Chapter 1: The Unexpected Error It started like any other routine task. You downloaded Oracle VM VirtualBox, ready to spin up a Linux virtual machine or perhaps a Windows test environment. You clicked "Finish" on the VM wizard, eagerly awaited the boot sequence, and then—disaster.
Instead of the operating system loading, you were met with a grim pop-up window. Perhaps it said "Failed to open a session for the virtual machine," or maybe it was more cryptic, mentioning a missing VCRUNTIME140_1.dll or a "Runtime Error."
This is a common plot twist in the world of virtualization. VirtualBox, though a powerful piece of software, relies on a supporting cast of code libraries to function. When the script calls for a specific line of code and the actor (the library file) is missing from the stage, the whole production grinds to a halt.
Chapter 2: The Diagnosis You checked the forums. You read the logs. The culprit wasn't VirtualBox itself, but the environment in which it was running.
VirtualBox is built using the Microsoft Visual Studio development environment. Specifically, it depends on the Microsoft Visual C++ Redistributable libraries to perform essential tasks like memory management and string manipulation. If your Windows installation is fresh, or if updates have removed older files, these libraries go missing. Chapter 1: The Unexpected Error It started like
In 2019 (and the versions surrounding it), Microsoft updated these libraries. If your system lacks the Microsoft Visual C++ 2015-2022 Redistributable, VirtualBox simply cannot run its core driver (VBoxSDS.exe) or the interface.
Chapter 3: The Search (Descargar) To fix the story, you need to retrieve the missing artifact. The keyword "descargar" (download) leads us to the official source.
Warning: This is the part of the story where you must avoid the villains—third-party "DLL download" sites. These are often full of malware. Always go to the source.
Chapter 4: The Installation Ritual
Once the vc_redist file is downloaded to your "Downloads" folder, the fix is straightforward. Chapter 4: The Installation Ritual Once the vc_redist
Note: If the installer says "Repair" or "Uninstall" instead of Install, it means you already have a version installed. Try clicking "Repair" to fix any corrupted files, or simply close the installer, as the library is already present and your error might be elsewhere.
Chapter 5: The Happy Ending The missing piece of the puzzle has been placed.
This time, the code executes flawlessly. The libraries load, the hypervisor initializes, and the virtual BIOS screen flashes before you. The story ends not with an error code, but with the successful boot of your virtual environment.

VirtualBox is not written entirely in assembly or low-level C. It relies heavily on C++ libraries provided by Microsoft to handle core operations such as:
When Oracle compiles VirtualBox, they link it against the Microsoft Visual C++ runtime. If those runtime files are missing from your system, Windows cannot interpret the code, leading to immediate crashes or installation failure. The 2019 version is particularly important because recent VirtualBox releases (version 6.1.x and 7.0.x) explicitly require this specific runtime.
