It means that Microsoft Visual C++ Redistributable (MSVCP140.dll) is missing from your Windows system.
This is a common runtime dependency for apps built with Visual Studio.
Fix Steps:
Download Microsoft Visual C++ Redistributable 2015–2022 (latest version):
Official Microsoft link:
https://aka.ms/vs/17/release/vc_redist.x64.exe (64-bit)
https://aka.ms/vs/17/release/vc_redist.x86.exe (32-bit)
If you’re not sure, install both x86 and x64.
Install the package(s).
Restart your computer.
Run vilanet again.
If you still get the same error:
Ensure your Windows is up to date.
If the program was built with a different runtime version, try reinstalling Visual C++ Redistributable for 2013 as well.
Avoid downloading MSVCP140.dll from random websites — that’s risky.
