Won't open, requires download again, Windows 7

Everything went smoothly during download then upon clicking to open the program, it asks to download again. Please help. I paid for this and I need it soon. Thanks

What does it ask to download?

It asks, “do you want this app to make changes to your device” --I did this process twice already.

It is not a request to download anything, it is a request to install on your hard drive (I think so, assuming that you’re running installer for Windows).

Did you complete the installation process (it includes a few steps in the installer window) ?

Yes, I did this process twice. It ran. It completed. Twice.

So now there should be “GanttProject” application shortcut in Start menu. Launch it.

It’s Java. It won’t download from any of my three browsers. I actually have Windows 10 and this just isn’t working out.

How can I get my money back? Thanks

What do you mean when you say “it’s Java”? Is there “GanttProject” shortcut in your Start menu? What happens when you launch it?
