Problem Installing on Windows 10

I don’t know if this forum is dead or not. But I want help! When i try to install on Windows 10, it says “Can’t write {Insert file name here.}” what does this mean and how can i fix it?

If it is during the install, it has to deal with Windows 10, not with Synfig.
Try to run the install in compatibility mode, as administrator or, better, switch to Linux!
By the way, are you a real human being or a bot?
