This walkthrough details solara .net runtime for Roblox players utilizing the Solara executor on Windows. Revised for 2026 and the newest Solara download (v0.1.7c).
If Solara is unresponsive when double-clicked, or Windows displays an error concerning .NET Desktop Runtime, you lack the runtime powering Solara's interface. Official Solara documentation confirms .NET Runtime 8.0 is a mandatory dependency.
Which Version Solara Demands
Solara depends on .NET Desktop Runtime 8.0 (x64). This is distinct from the older .NET Framework included with Windows. You must get the modern .NET runtime package provided by Microsoft.

Installed Already but Solara Fails to Launch?
If the runtime appears among installed programs yet Solara fails to run, files might be corrupted. The official Solara instructions suggest launching the .NET installer again and picking Repair.
- Relaunch that same .NET 8 installer file.
- Once the setup window opens, choose Repair rather than Install.
- Allow it to finish, reboot your PC, and launch Solara again.
Still refusing to start? The additional required prerequisite is the Visual C++ Redistributable. Install both, restart Windows, and test again. If Solara opens but fails to attach, consult Solara Not Attaching.
