Remote Control Web Interface "varsion.txt" is missing

Hello, I am trying to install Remote Control Web Interface, but no matter how many times I try, I get the error “ENOENT: no such file or directory, open ‘C:\Program Files\Epic Games\UE_4.26\ Engine\Plugins\Marketplace\RemoteControlWebInterface\WebApp\Server\build\version.txt’” error.
There is no “\build\version.txt” under Server.
I have re-installed the plugin many times on the engine and still no file. What is the solution?
