1. Check to see if the application is already installed
If already installed, exits the script. Otherwise proceeds with section 2.
#>

$appName = 'Timus Connect'
$RegUninstallKey = 'HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\*'
$installedApplication = Get-ItemProperty -Path $RegUninstallKey | Where-Object {$_.DisplayName -like "*$appName*"}

if ($installedApplication) {
Write-Host "Application is already installed, exiting script"
} 
else {
Write-Host "Application is not installed."

2. Check to see if this is a desktop or laptop by looking for a battery

#!#! Delete this whole line if you want to disable this section #!#! #>

$systemType = "Unknown"
$BatteryStatus = (Get-WmiObject -Class Win32_Battery -EA SilentlyContinue).Status

if ($BatteryStatus) {
$systemType = "Laptop"
} else {
$systemType = "Desktop"
}
Write-Output "This device is a" $systemType

#2.1 At this time I am only automating the Timus installation on laptops

if ($systemType -eq "Desktop") {
Write-Output "The device is a desktop, exiting script."

}

3. Does the download destination exist?
If not, create download directory
Default download directory is "C:\temp\Timus Networks"
#>

$dlFolder = "C:\temp\Timus Networks"
$dlFolderTest = Test-Path -Path $dlFolder
$dlDest = "$dlFolder\Timus-Connect.exe"
$dlUrl = "https://repo.timuscloud.com/connect/Timus-Connect.exe"
$tempFolderExists = Test-Path -Path "C:\Temp"

if ($dlFolderTest -eq $true) {
Write-Output "Download directory exists, continuing with download."
}
else {
Write-Output "Download directory does not exist, creating directory"
New-Item -ItemType Directory -Path $dlFolder -Verbose -ErrorAction Stop
}

4. Starting download to destination
Will try three different methods to download the file: Invoke-WebRequest, WebClient, and finally Start-BitsTransfer.
If all three fail, the script will exit with a failure.
#>

try {
Write-Output "Trying to download..."
Invoke-WebRequest -Uri $dlUrl -OutFile $dlDest
Write-Output "Invoke-WebRequest download was successful, moving on to installation..."
}
catch {
Write-Output "Invoke-Webrequest failed, trying webclient download..."
try {
$webClient = New-Object System.Net.WebClient
$webClient.DownloadFile($dlUrl, $dlDest)
Write-Output "WebClient download was successful, moving on to installation"
} 
catch {
Write-Output "WebClient download failed, starting BitsTransfer..."

try {
Start-BitsTransfer -Source $dlUrl -Destination $dlDest
Write-Output "Downloaded successfully with BitsTransfer, moving on to installation..."
}
catch {
Write-Host "All methods failed. Unable to download the file. Exiting."
Exit 1

}
}
}

Upon error, the script will exit.
Checks registry for uninstall key for Timus Connect.

#>
Start-Process -Wait -FilePath $dlDest -ArgumentList "/S" -PassThru -ErrorAction Stop

#Check for successful install
$appName = 'Timus Connect'
$RegUninstallKey = 'HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\*'
$installedApplication = Get-ItemProperty -Path $RegUninstallKey | Where-Object {$_.DisplayName -like "*$appName*"}

if ($installedApplication) {
Write-Host "Application is installed."
} else {
Write-Host "Application is not installed."

6. Performs cleanup of created files/folders
If download root existed prior to script, will only remove newly created folder.
For example, if C:\temp already existed, the script will only remove C:\temp\Timus Networks
and not C:\temp as a whole.

If download root did not exist, it will delete the whole folder

#>

if ($tempFolderExists -eq $true) {
Write-Output "Temp folder existed prior to download, only removing" $dlFolder
Remove-Item -Path $dlFolder -Recurse -Force
Write-Output "Cleanup complete, exiting..."
Exit 0
}
else {
Write-Output "Temp folder did not exist prior to script, deleting Temp folder..."
Remove-Item -Path "C:\Temp" -Recurse -Force
Write-Output "Cleanup complete, exiting..."
Exit 0

}
