I have been trying to get this to work via a game control panel TCAdmin.
$ModPg1 = Invoke-WebRequest "http://steamcommunity.com/sharedfiles/filedetails/?id=731604991"
$ModVer1 = ($ModPg1.ParsedHtml.getElementsByTagName('div') | Where{ $_.className -eq 'detailsStatRight' } ).innerText | Select -Last 1
If I run this cmdlet via a program like TCAdmin (or task scheduler), I get the following error....
Invoke-WebRequest : The response content cannot be parsed because the Internet Explorer engine is not available, or Internet Explorer's first-launch configuration is not complete. Specify the UseBasicParsing parameter and try again.
Explorer is installed, and set up. The script works just fine if I run it manually.
My guess is there is a way to get TCAdmin to run the scripts the same way I would as a windows User.
Cant find a way nearly as simple to scrape the info 'm looking for.
As for this...
get TCAdmin to run the scripts the same way I would as a windows User.
For any app to run as a user, that users profile must be used on the host where the code is to be run. You cannot natively run PoSH on a host as another user context. This is not a PoSH issue, it is a Windows User Principal security boundary. There are tools that let you do this. For example SysInternal PSExec and AutoIT. Yet as stated that error is pretty specific. The user profile for Internet Explorer has not been created and that only happens when you use IE at least once.
So, as Adam points, out, use the setting the error message states to use or use your code to start IE at least once.
$SomeUrl = 'https://stackoverflow.com'
$ie = New-Object -com internetexplorer.application
$ie.visible = $true
$ie.navigate($SomeUrl)
while ($ie.Busy -eq $true) { Start-Sleep -Seconds 1 } # Wait for IE to settle.
Again, if trying to run this in the context of another user, the two above tools will get you there, but you still have to fire up IE to have a profile for it.

When I am running commands or installing software remotely using PowerShell - Invoke-Command etc I would like sometimes to be able to show a message on the remote screen so the user knows something is happening, or when work done etc.
I would like to if possible make this message look as professional as possible, e.g. better than just a standard winform message box if it can be done? perhaps more the style of the Windows 10 ones with coloured background and use of image if possible.
Spent a while googling but most seem to relate to using obsolete methods such as net-send or using msg.exe.
Thanks

So the issue really isnt creating the messagebox itself, its having it show on the users session.
So when you run a command against a system, youre using your creds to run the command therefore it wont show in the users session. You can get around this by running it in the users context using a task scheduler. I have a script that does all this for you but, id hate to recreate the wheel and will have to wait till monday (when im at work) to post it here.
It accepts user input in your sessions that outputs it to a vbs, which then copies it over the message to the users machine, and a task schedule is set to run immediately for the user thats logged in.
edit: The script is this without the task scheduler. I just invoke gwmi win32_computersystem | Select -ExpandProperty username to get the current user logged in and add it to the task.
#Prompt for messge
$strMSG = Read-Host -Prompt "Enter message"
#deleting vbs if it exists
del C:\brief\test.vbs
#creating vbs from scratch so it doesnt override
New-Item C:\brief\test.vbs
#Appending each the values to a seperate line
Add-Content C:\brief\test.vbs 'Set objShell = Wscript.CreateObject("WScript.Shell")'
Add-Content C:\brief\test.vbs "strText = `"$strMSG`""
Add-Content C:\brief\test.vbs 'intButton = objShell.Popup(strText,0,"Computer Support",48)'
#calling on the script
& cscript C:\brief\test.vbs
Found a great solution here which appears on quick testing to work well for displaying a toast notification on a remote machine

I'm trying to download an file from a particular website by clicking on the file icon. Website login works but i'm hoping to use keystroke "TAB" to navigate to the excel file and finally key "Enter" to download. Ran the code but resulted in the Powershell text of "FALSE". Any advice is appreciated! Thanks.

Why are you doing that vs using web scraping to find the link you are trying to hit, and use the link URL directly?
Your post is really a duplicate of this Q&A.
Use PowerShell to automate website login and file download
SendKeys could work, but they are very hinky and on different systems may not function as you'd expect. There are better tools dedicated to do this, AutoIT, Selenium, WASP
--- That WASP tool still works, but has not been updated in a long while.
Using PowerShell 2.0 With Selenium to Automate Internet Explorer, Firefox, and Chrome
Internet Explorer
Next you want to obtain the Internet Explorer driver from this site. I
recommend version 2.41 because “as of 15 April 2014, IE 6 is no longer
supported”. This must reside in your current PATH so in your script
you may want to modify your PATH to ensure the executable
(IEDriverServer.exe) can be found there. If you’re wondering whether
to get the 32-bit or the 64-bit version, start with the 32-bit even if
you’ve got a 64-bit Windows.
At this point you’ll want to quickly instantiate Internet Explorer and
navigate somewhere. Great. Let’s do it.
# Load the Selenium .Net library
Add-Type -Path "C:\selenium\WebDriver.dll" # put your DLL on a local hard drive!
# Set the PATH to ensure IEDriverServer.exe can found
$env:PATH += ";N:\selenium"
# Instantiate Internet Explorer
$ie_object = New-Object "OpenQA.Selenium.IE.InternetExplorerDriver"
# Great! Now we have an Internet Explorer window appear. We can navigate to a new URL:
$ie_object.Navigate().GoToURL( "http://www.bbc.co.uk/languages" )
# This worked! The call won’t return until the page download is complete.
# Next let’s click on a link from the link text:
$link = $ie_object.FindElementByLinkText( "Spanish" )
$link.Click()
# display current URL
$ie_object.Url

Update for the OP
As for...
However the file does not have a redirected URL
Then you need to look deeper at the site, to find the anchor to the file that you can force click on.
Example:
# Scrape a web page with PowerShell
$w = Invoke-WebRequest -Uri 'https://www.reddit.com/r/PowerShell'
$w | Get-Member
$w.AllElements
$w.AllElements.Count
$w.Links.Count
$w.Links
$w.Forms
$w.Forms.Fields
$w.Forms[0]
$w.Forms[0].Fields
$w.RawContent
$w.ParsedHtml
once you find tag names, or the like, you need to parse that to get stuff out of it.
$w.AllElements | Where-Object -Property 'TagName' -EQ 'P' | Select-Object -Property 'InnerText'
For tables you have to dig more.
Extracting Tables from PowerShell’s Invoke-WebRequest
Fairly new to PowerShell and exploring its capabilities. I have created the following script to automatically log in to LinkedIn, but it opens the web page and does nothing else, can some please assist? I wish to use the script to log in to a web status page and search for issues for alerting purposes, thank you.
PowerShell Script
$username = "Username"
$password = "Password"
$ie = New-Object -com InternetExplorer.Application
$ie.visible=$true
$ie.navigate("https://www.linkedin.com")
while($ie.ReadyState -ne 4) {start-sleep -m 100}
$usernameElement = $ie.document.getElementById("login-email").value= "$username"
$ie.document.getElementById("login-password").value = "$password"
$ie.document.getElementById("login-submit").submit()
start-sleep 20
OK, took me a while, but I figured out the issue. On LinkedIn specifically, the login-submit button has two notable properties: isDisabled and disabled. Those need to be both changed to $true before it can be clicked. Also, change the function called on it from .submit() to .click(). Also, a quick tip: After the script is done (I'm not sure if this is still true, because you seem to manually close it afterwards), $ie is kept under your script's management. To release it, call this command (after you manually close it, so it might be hard to get in there):
[System.Runtime.Interopservices.Marshal]::ReleaseComObject($ie) #>
Not really sure why, I just know it keeps it out of the way and is apparently equivalent to killing it from the task manager.
I created PowerShell script wich install an application on computer (windows 7).
This script is in GPO and deployed with GPO at logon users. This worked fine, but I want that at the end of installation, my powershell script send at the current logged user on computer a message like "Reboot your computer please".
I tested many things but I don'tview popup, maybe because my script are execute with admin rights (not with user rights).
Test :
#$wshell = New-Object -ComObject Wscript.Shell
#$wshell.Popup("Operation Completed",0,"Done",0x1)
[Windows.Forms.MessageBox]::Show(“My message”, , [Windows.Forms.MessageBoxButtons]::OK, [Windows.Forms.MessageBoxIcon]::Information)
Your script may be popping up the message but then closing the PowerShell console immediately after, removing the popup. Try waiting on the result of the popup before closing the PowerShell instance:
$wshell = New-Object -ComObject Wscript.Shell
$result = $wshell.Popup("Operation Completed",0,"Done",0x1)
You need to load the assembly providing the MessageBox class first, and you cannot omit the message box title if you want to specify buttons and/or icons.
Add-Type -Assembly 'System.Windows.Forms'
[Windows.Forms.MessageBox]::Show(“My message”, "", [Windows.Forms.MessageBoxButtons]::OK, [Windows.Forms.MessageBoxIcon]::Information)
# ^^
You can use an empty string or $null here, but simply not providing a value (like you could do in VBScript) is not allowed.
As a side-note, I'd recommend avoiding typographic quotes in your code. Although PowerShell will tolerate them most of the time, they might cause issues sometimes. Always use straight quotes to be on the safe side.
Edit: Since you're running the script via a machine policy it cannot display message boxes to the logged-in user, because it's running in a different user context. All you can do is have a user logon script check whether the software is installed, and then display a message to the user. This works, because a user logon script running in the user's context.
I am attempting to get a script working that does not use invoke-webrequest. The problem I am having is that when I run the script a popup prompt occurs, the popup consists of the following message;
"Windows Security Warning
To allow this website to provide information personalized for you, will you allow it to put a small file (called a cookie) on your computer?"
with yes no response from user
The code I am executing is the following:
$ParsedHTML = New-Object -com "HTMLFILE"
$webresponse = New-Object System.Net.WebClient
$webresponse.Headers.Add("Cookie", $CookieContainer.GetCookieHeader($url))
$result = $webresponse.DownloadString($url)
$ParsedHTML.IHTMLDocument2_write($webresponse)
$ParsedHTML.body.innerText
The main problem with this code is that the $url I am using part of the weblink checks to see if cookies are enabled and this code causes a returned value of disabled.
My question, is there a way to handle the cookie request without changing the output response from the test url site.
Note: This script will be automating a process over hundreds of remote computers and thus having an unhandled popup will just prevent the script from running.
I found the answer in another SO question Using Invoke-Webrequest in PowerShell 3.0 spawns a Windows Security Warning
add the parameter -UseBasicParsing
Technet https://technet.microsoft.com/en-us/library/hh849901.aspx notes that the parameter stops the DOM processing. and has the caveat "This parameter is required when Internet Explorer is not installed on the computers, such as on a Server Core installation of a Windows Server operating system."
So, you mileage may vary.
