Davinci Resolve install fails

Hello,
Despite multiple downloads and installations of Davinci Resolve ver. 18.1.4 from the official website after installing there is no Davinci Resolve in the system, only additional components: RAW Player, RAW Speed ​​Test, Control Panels, Fairlight Studio Utility.
I was looking for information in the forum. I found that some components might result installation failure. So I didn't select additional components, trying to install less and less then even unchecking all of them but still no result.
After information from a friend that version 18 is not working properly, I tried to install the latest 17 version 17.4.6, unfortunately, the above steps also did not work.
I'm surprised because I just was about to buy the studio version and tried to install the free version before buying the D.R. Studio. Now I'm afraid to buy the paid version if the basic version doesn't work. My Desktop: Win 11 Pro, CPU Intel i9-13900F 2.0 GHz, GPU Geforce RTX 4080, 128 GB RAM, This configuration supposed to be efficient enough to handle your program.
I would like to ask you for help and information on how to perform the installation successfully.
Kind regards,
Jordan

Version 18 is working fine for most of us and your machine should be up to it.
Did you get the installer for the free version or the one for Studio?

I tried to install free versions multiple times as I mentioned in my post above: the latest Davinci Resolve 18 and latest 17 to test it out before purchasing the studio version. None of installations work out. Only the components mentioned above appear in the system, but no Davinci Resolve itself. The computer is pretty decent with all updates and I haven't had any problems with all the softwares used so far, even those that require high performance. I don't want to risk buying the software that wouldn't work. Hence I would like to shift my work flow into Davinci. Any solutions to help become the Davinci customer?
