On running Vensim, I get the error “api-ms-win-core-version-l1-1-1.dll is missing”.

If you are running Windows 7, this is why you are seeing this message. Since Microsoft do not support Windows 7, we cannot recommend it’s use either. You can try the Microsoft link below and update the Universal C Runtime, but Vensim will still likely not work.

Your best option is to upgrade to Windows 10. There is also a lot of discussion on this that you can find using Google.

For Windows 8/8.1, your operating system is probably not up to date. Visit the following site, download and install the Universal C Runtime for your system.
