Web Client setup error

Web Client setup error

I'm trying to setup webclient on a computer.
Server & WebClient computer is Windows10, Zenon version is 8.10 Build 57250.

The webserver is a staqndalone Zenon runtime computer, ISS is running and Zenon webserver is running.

First I tried to click on the webclient setup shortcut that is displayed on the http://IP.xxx/zenon page, but it failed, freezed and nothing happend.
Then I tried to mount Zenon install dvd iso, started setup selected Webclient from the installwizard, but then I got this error 1904

Any Ideas how to proceed?
/Regards Tobias
