How to run commands on a remote computer using PSExec and PowerShell? - powershell

Question

I am trying to install an .exe program remotely to many workstations in the domain.
The command I am trying to run in the remote computer's PowerShell instance:
.\PsExec.exe \\$Computer /s cmd /c %SystemRoot%\system32\WindowsPowerShell\v1.0\powershell.exe -ExecutionPolicy Unrestricted -File \\FileShare\Software\DellSupportAssist.ps1
And the script I am calling in the command above:
#Retrieves a list of computers in AD.
$Computers = Get-ADComputer -Filter 'Name -like "Workstation*"' | Select-Object -ExpandProperty Name
ForEach ($Computer in $Computers) {
#Opens a remote session into the computer.
.\PsExec.exe C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe \\$Computer
#Installs Dell SupportAssist for each computer
Invoke-WebRequest -Uri "https://downloads.dell.com/serviceability/catalog/SupportAssistInstaller.exe" -OutFile "C:\Users\$env:Username\Downloads\SupportAssistInstaller.exe"
Start-Process "C:\Users\$env:Username\Downloads\SupportAssistInstaller.exe" -ArgumentList "/q" -Wait -NoNewWindow
Write-Host "Installing Dell SupportAssist on $Computer" -ForegroundColor Green
#Checks whether Dell SupportAssist was successfully installed or not
if (Get-WmiObject -Class win32_product -ComputerName $Computer | Where {$_.Name -match "Dell Support*"} | Select-Object -ExpandProperty Name) {
Write-Host "Dell SupportAssist was successfully installed on $Computer" -ForegroundColor Yellow
} else {
Write-Host "Dell SupportAssist was not successfully installed on $Computer" -ForegroundColor Red
}
exit
}
I am having the following issues:
'Target name incorrect' (for half of the computers in the domain.)
.\PsExec.exe : The term '\FileShare\Software\DellSupportAssist.ps1' is not recognized as the name of a cmdlet, function, script file, or operable (for the computers I can connect to in the domain)
