Installing and running on Windows

Running

Download the latest Windows version (zip file)
Extract it to any folder (hint: system folders, like C:\ or C:\Program Files aren't recommended: the built-in updater won't have permission to write, and config changes might not be saved)
In the extracted folder, run molflow.exe
Hint: you might have issues if your system locale is set to have a comma (,) decimal (typically: German Windows installations.) You can change this in Control Panel's "Region" settings.

Recent Molflow versions are developed in Visual Studio Community 2019 on Windows 10. They rely on the Visual C++ 2015 redistributable package (x64 version) and the Universal Windows CRT package.

The Visual C++ 2015 redistributable is shipped with Molflow (vcruntime140.dll and vcruntime140_1.dll and msvcp140p.dll in the program directory)
The Universal Windows CRT package is already present on Windows 10, and comes as a Windows Update package on older systems (Windows Vista to Windows 8.1)

If Molflow is not running (missing api-ms-win-crt-runtime-l1-1-0.dll, for example), do the following:

Make sure all Windows Update packages are installed (sometimes new are available after restart)
Install the latest Microsoft Visual C++ Redistributable
