This tutorial explains solara visual c++ aimed at Roblox users running the Solara executor on Windows. Revised for 2026 alongside the newest Solara download (v0.1.7c).
Whenever Solara fails to start and Windows prompts with alerts such as "VCRUNTIME140.dll could not be located" or "MSVCP140.dll is missing", the Microsoft Visual C++ Redistributable must be installed. According to official Solara instructions, this prerequisite is essential for launching the executor.
Selecting the Correct Edition
You will need the Visual C++ 2015–2022 Redistributable. Although you run 64-bit Windows, install both the x64 as well as x86 installers — numerous programs rely on 32-bit dependencies, making the x86 file frequently necessary.
Obtain them straight from official Microsoft sources:
Get x64 (64-bit) Get x86 (32-bit)
Direct permanent mirrors for Microsoft's most up-to-date supported builds.
Setup Walkthrough
- Get both files
vc_redist.x64.exeandvc_redist.x86.exe. - Execute the x64 package initially, agree to the terms, and allow it to complete.
- Launch the x86 setup afterward. Should it report an existing newer build, ignore it and proceed.
- Reboot your computer. A reboot ensures all DLL components register correctly.
- Open Solara with administrative rights and test it once more.
Avoid grabbing standalone DLL files from third-party sites. Standalone DLL downloads frequently carry malware and rarely resolve errors since these libraries require companion files from the full suite. Stick strictly to genuine Microsoft installers.
Encountering the Bug Despite Prior Installation?
Should the runtime appear under installed software while Solara continues to throw errors, the setup might be damaged. Run a repair:
- Navigate to Settings → Apps → Installed apps.
- Locate Microsoft Visual C++ 2015-2022 Redistributable (x64).
- Select the three dots → Modify → Repair.
- Perform the identical action on the x86 release if it exists.
- Reboot your machine and re-launch Solara.
Still refusing to launch? The subsequent requirement is the .NET Desktop Runtime. Install it as well, then try again. If Solara launches but fails to attach, check Solara Failing to Attach.
