I recently downloaded DesignSparkElectrical_v1.3 onto a Windows 8.1 PC. But it would not run as an api-ms-win-crt .dll was not installed. It seems that it is not part of the Microsoft Visual C Redistributable included with the download. What I had to do was go to the Microsoft support website and download this update that allows programs created on Windows 10 to run on Windows 8.1

Note this takes a long time to run but I found it worked.
