If you have the latest Microsoft Visio version installed and VSL files still not open, select it as default to manage VSL files. We have free online VSL file apps to view, edit, convert, merge, split, compare VSL files without installing anything. Some software developers introduce formats along newer application versions. The reason Visio cannot handle VSL files may be the software is outdated. Check if you have Visio latest version. All formats previous Visio versions handled should open in latest too.
If problem persists, assign Microsoft Visio as default for VSL files on your device. Install Microsoft Visio if not present. Enter its name in system search. Visio absence often overlooks but installing mostly fixes opening problems.
VSL files are Visio add-ons. Visio and third parties create and distribute them. VSLs extend Visio functionality. They are DLLs configured for Visio.
