should look like something like this:

$ErrorActionPreference = 'Stop'; # stop on all errors
$toolsDir   = "$(Split-Path -parent $MyInvocation.MyCommand.Definition)"
$fileLocation = Join-Path $toolsDir 'scinstalls.exe'
$url        = '' # download url, HTTPS preferred
$url64      = '' # 64bit URL here (HTTPS preferred) or remove - if installer contains both (very rare), use $url
 
$packageArgs = @{
  packageName   = $packageName
  unzipLocation = $toolsDir
  fileType      = 'exe' #only one of these: exe, msi, msu
  url           = $url
  url64bit      = $url64
  file         = $fileLocation
 
  softwareName  = 'Soft Cleaner' #part or all of the Display Name as you see it in Programs and Features. It should be enough to be unique
 
  checksum      = ''
  checksumType  = 'sha256' #default is md5, can also be sha1, sha256 or sha512
  checksum64    = ''
  checksumType64= 'sha256' #default is checksumType
 
  silentArgs   = '/VERYSILENT /SUPPRESSMSGBOXES /NORESTART /SP-' # Inno Setup
  validExitCodes= @(0, 3010, 1641)
    
}
 
Install-ChocolateyPackage @packageArgs # https://chocolatey.org/docs/helpers-install-chocolatey-package

NOTE: this is just an example, not the solution ;-)

additonally: drop $url, $url64 and any other non-needed parameter.
thus, add actual checksum values
