The GitHub Version works just fine on Windows 10 64bit (Fresh Install) … in-fact I'm running the 'Next Release' (1903), which has it's "Issues" and it works just fine.
There's no need to actually Build / Compile the Project, as a Pre-Build (with Certificate and Authentication Checks Removed) is packaged with it.
Easiest way to ensure it Downloads Properly is to install Visual Studio Community (2017 / 2019), then on GitHub make an account so you can use the dropdown to select "Open in Visual Studio"
This will prompt the GitHub Source Clone, by default it will be C:\Users\[Username]\Source\Repos\Dark-Basic-Pro
Use the File Browser to get to said Directory, then copy the [Install] Folder
I'd recommend putting it in C:\Program Files (x86)\ and renaming it "Dark Basic Professional" or such... makes it easier to find.
Right-Click "Launch.exe" and create a Shortcut (Drag it to the Desktop or Pin to Start)
I've attached an updated darkbasic.ico … it looks cleaner, and I'd recommend using it to have something more recognisable than the weird blue TGC Circle one that's used by default.
Start via the Shortcut., then go to Tools >> Options
Copy-Paste "C:\Program Files (x86)\Dark Basic Professional\Compiler\DBPCompiler.exe" (or wherever you actually copied it too) in the Compiler Filename (or manually use the Browse just to make sure)
Then select Tools >> Rebuild Keywords
And... well that's it.
There's no need for the DirectX 9 Runtime, it'll just work "As-Is" and as flawless as ever did in the past.
You might have some issues with Temporary Projects, so just be sure to create a new 'Blank' Project... AND I'd also recommend creating a Shortcut of Editor/EditorNew.exe instead of Launch.exe to get rid of the Broken GDI-Based "Link" Page that now only forwards to an ISP "Broken Link".
I think it used to connect to the Website or something, but who knows at this point.
