You may have recently noticed a new program called 3D Vision Photo Viewer on your computer and are wondering how it got there. This software is typically installed as part of the driver package for NVIDIA graphics cards, which are popular among gamers and computer enthusiasts. When you install the driver for your NVIDIA GPU, the 3D Vision drivers and software are included by default. This is because 3D Vision Photo Viewer is designed to work in conjunction with NVIDIA's 3D Vision technology, which allows for a more immersive 3D viewing experience on compatible monitors and displays.

Another common way 3D Vision Photo Viewer ends up on your computer is through the installation of other NVIDIA software, such as GeForce Experience. GeForce Experience is a companion application for NVIDIA graphics cards that helps users optimize game settings, update drivers, and capture and share gameplay footage. As part of the GeForce Experience installation, the 3D Vision driver and software may also be included.

It's also possible that the 3D Vision Photo Viewer was installed by mistake or as part of a bundled software package. Some programs, especially those downloaded from less reputable sources, may include additional software as part of their installation process. This can sometimes lead to the unintentional installation of programs like 3D Vision Photo Viewer without the user's knowledge.

If you're not sure how 3D Vision Photo Viewer got on your computer, it's always a good idea to review the list of installed programs in your system settings. This can help you identify when the software was installed and if it was part of a larger package. From there, you can decide whether you want to keep the software or uninstall it if you don't have a use for it.

In any case, 3D Vision Photo Viewer is a legitimate piece of software from NVIDIA and is not considered malware or a virus. It's designed to enhance the viewing experience for users who own compatible NVIDIA graphics cards and monitors. If you have no use for the software, you can safely uninstall it through the standard Windows uninstallation process. If you do want to use the 3D Vision functionality, you may want to explore its features and capabilities to see if it's a good fit for your needs.

At the end of the day, 3D Vision Photo Viewer is just one of many pieces of software that can find their way onto your computer through various installation methods. By understanding how it typically gets installed, you can make an informed decision about whether to keep it or remove it from your system.
