Alternatively, if you prefer using the command line, you can use 7-Zip or similar tools.
Run a malware scan (Malwarebytes + Windows Defender offline scan). Cracked KSP repacks have occasionally included miners or injectors. Check file sizes: a clean KSP 1.12.5 + DLCs is ~3.5 GB compressed, ~6 GB extracted. If the .rar is 2 GB or less, it’s likely trimmed (missing assets, reduced textures).
Bottom line:
The .rar will run, but for long-term modded KSP, buy the official version. If you’re just testing the game, the repack is fine — just treat it as a demo and purchase if you enjoy it. The KSP community strongly supports the developers (even after KSP 2’s disaster) because KSP 1 remains a masterpiece.

Understanding Kerbal Space Program v1.12.5: The Final Frontier of KSP1

The "OnFinalApproach" Update: Final optimizations to the game engine to ensure smoother performance on modern hardware.

While Kerbal Space Program 2 exists, the original KSP v1.12.5 remains the preferred choice for a significant portion of the community.
Performance: v1.12.5 is highly optimized and runs well on a wide variety of hardware, from high-end rigs to basic laptops.
The Modding Ecosystem: With over 10 years of development, the mods available for v1.12.5 are transformative. You can add high-definition clouds with EVE, realistic physics with Principia, or entirely new star systems.

When searching for files like "kerbalspaceprogramv1125rar," it is crucial to prioritize digital safety.
