Error importing a demo

Hello, I downloaded the WordPress theme “Finance”, when I wanted to continue configuring my website with this theme, I noticed that the elements of the demo are missing, and when using the “One Click Install” plugin I get the error “404- Not Found”, Has anyone been able to install it without problems?

Have you contacted the theme author?

Yes, I haven’t received an answer.

You should wait for the support - that is being provider for free by the author.
If you don’t want to wait or up for paid support, I can offer installation service at Studio

Please give them time to get back to you.
In the meantime you can check the theme documentation, hopefully you will get necessary help.
