The download link on the main page is currently incorrect.
It goes to: https://www.donationcoder.com/Software/Mouser/screenshotcaptor/downloads/beta/ScreenshotCaptorSetup.exe
But that does not work.

I then modified the url to: https://www.donationcoder.com/Software/Mouser/screenshotcaptor/downloads/ScreenshotCaptorSetup.exe (IE Without the beta and it works, and does download 2.44.01 correctly)

Hope this helps anyone else currently trying to download it.
