The only listed versions of Windows that are compatible with DirectSOFT32 - Programming are Windows 98, Me, NT4, 2000, and XP. As you can see, there is no Windows 10 compatibility available. You could try running it in Compatibility mode using Troubleshoot Compatibility after right clicking on the setup package, but I doubt it will work for this type of applications.
Since there is no Windows 10 compatibility, the only way to run it on Windows 10 is through virtualization. This implies installing Windows XP in a virtual machine and work with it from there. You'll need Virtualbox, a Windows XP install disc/ISO and a tutorial.
