Can't find SteamSetup.exe filepath

[imotalus]

When trying to instal steam by double clicking on SteamSetup (it has the properties of a .exe file) it takes about 3 minutes to get the pop-up E:\Downloads\SteamSetup.exe doens't exist, check your filepath and try again.

I've been looking here and didn't find this specific problem (did find the SteamService one).
Tried changing the name to SteamSetup.exe, but same issue. Except is says, E:\Downloads\SteamSetup.exe.exe doens't exist. So changing the name isn't the issue.

Tried downloading the SteamSetup file a bunch of times, no changes, tried restarting laptop, no changes, tried administrator, no changes.

Windows 10, clean installation since a few days
E is my HHD (was called D before but it changed to another HHD placement).

Am I missing something or could it be another problem?

Hm. That's odd. See if downloading SteamSetup.exe to C: works.

Same issue, no changes

I haven't suggested this in a very very long time but you can open up steamsetup.exe in something like 7-zip and pull out Steam.exe.

Place it wherever you'd like to install Steam (I recommend something like C:\Games\Steam\) and then just run it, should install Steam there as normal.

hmm, could work. I'll try then when I have the time

The same issue occurred when trying to install 7zip (hadn't downloaded it yet due to clean installation)
It can't find the filepath and I tried the solutions give in this discussion again here. Could the download folder itself have an issue?

Issue is much bigger after some trying doing stuff.
.exe files can't be found anymore. That also goes for system files like taskmanager. registery edit doens't work either and a lot of other features using a .exe file.

Problem is windows itself.
Something went wrong in the clean installation. I'll be upgrading to windows 10 pro and see is that works. Otherwise a home edition and try again
