Start-process: both positional parameter and can't locate file specified - powershell

Question

Ok, So I am working on the powershell remote deployment of software to ADUsers.
I have remote access to the computer and all, no problems there.
Right now I am at the point where I have a exe file from Ninite to just install 7zip onto the client pc just to see when it works so i can start deploying some bigger programs to it.
The guide I have found to help me deploy out the software for now looks like this:
Invoke-Command -ComputerName *REDACTED* -Scriptblock {
Start-Process C:\Users\Administrator\Documents\ninite_7_zip\Ninite 7Zip Installer.exe '/silent' -wait
}
When I do run this code, I get the error:
A positional parameter cannot be found that accepts argument 'Installer.exe'.
So I thought to myself, that it might be because of the spaces in the name. So therefore I changed it to:
Invoke-Command -ComputerName *REDACTED* -Scriptblock {
Start-Process C:\Users\Administrator\Documents\ninite_7_zip\Ninite_7Zip_Installer.exe '/silent' -wait
}
And ofcourse also changed it's name within the folder to match the "newly made" code.
But the error now changed into:
This command cannot be run due to the error: The system cannot find the file specified
Even though I use Powershell ISE, and I used it's guideboxes when writing, to enter the folder and find it, when I wrote the directory.
My only goal in this, is that I want to remotely run and complete this installer on the client PC when deployed from the DC upon which the file lies.
Anybody got a qualified guess? Or maybe even so, a solution.
Thanks in advance for your kind answers.

When I do run this code, I get the error:
A positional parameter cannot be found that accepts argument 'Installer.exe'.
You'll want to use quotation marks to qualify path names with spaces in them:
Start-Process 'C:\Users\Administrator\Documents\ninite_7_zip\Ninite 7Zip Installer.exe' '/silent' -wait
But the error now changed into:
This command cannot be run due to the error: The system cannot find the file specified
Even though I use Powershell ISE, and I used it's guideboxes when writing, to enter the folder and find it, when I wrote the directory.
ISE is not smart enough to realize that the scriptblock is to be executed on a remote computer, so it completes the path based on your local file system.
You still need to copy the executable to the remote machine in order to execute it:
# first copy the installer to remote file system
$remoteSession = New-PSSession -ComputerName $computerName
$localInstaller = 'C:\Users\Administrator\Documents\ninite_7_zip\Ninite 7Zip Installer.exe'
$remotePath = Invoke-Command -Session $remoteSession -ScriptBlock { $env:TEMP }
Copy-Item $localInstaller -Destination (Join-Path $remotePath "7zInstaller.exe") -ToSession $remoteSession
# now we can invoke the executable on the remote machine (re-using the same remoting session)
Invoke-Command -Session $remoteSession -ScriptBlock {
Start-Process (Join-Path $env:TEMP "7zInstaller.exe") '/silent' -Wait
}
# clean up
$remoteSession |Remove-PSSession |Out-Null
