Why version 6 is not appear on my PC?

I had window10 x64 version. I had download libre office 6.0.0_Winx64_sdk.msi but after installed I had the icon of the previous version 5.4.6.1x64msi and my document still get open with 5.3.
Cannot see the icon short cut. Why?
Before had download also version 5.3.7 but had similar result.
I had delete all and now I will tray to download 5.3.7
Cheers

You have downloaded a wrong installer, namely, SDK (=software development kit). Download the application from the download page. Unless you understand what you are doing (and you don’t understand), simply click on the big yellow Download button.

Thanks gabix, I was sospetting that! I had removed and download version 5.4
All in order! Still learning and ran out of time Old!
