@adshung Everything works fine for me, even on several machines. Most likely, the problem is with some kind of build (did you download it from the official Microsoft website?). Maybe you don't have enough space. Try running the installation as an administrator.
@docker0004 If you try to register an account as is, will there be an error? I mean, maybe you shouldn't have a captcha?
Please attach a test project that reproduces the problem.
