To write about instagram on pc?

I have a problem with instagram on my laptop. I wanted to write chats and have already watched videos. But in which one had to download an app and if I clicked on the screen is white… Do you know why the app does not work for me?

Uninstall App once and reinstall. Should help.

But I have not installed them. I want to install them but there's only a white page

You go to Windows 10 in the Microsoft Store and there looking for Instagram. Then you can install it.
