Support for Windows 7, 8

[L3337]

After disabling the check for Windows 10 or above, Stargate DAW installs on Windows 8.1, but crashes immediately on start up. The fix is to install the Visual C++ 2015 Redistributable, at which point Stargate DAW seems to work perfectly.

However, installing the VC2015R during the installation would have one of the following side effects:

• Much larger installer
• Internet access required during installation

It's not apparent that there are actually any prospective users on Windows 8, making both of those options pretty unpalatable. Furthermore, Windows 7 is no longer supported by recent Python versions. and Windows 8.1 is unsupported by Microsoft as of Jan. 10, 2023. However, if there is a significant number of users on Windows 8.1 who would like Stargate DAW to support it, let yourselves be known in this issue, and we will start bundling the VC2015R with the installer.
