PowerShell Help

I’m trying to convert a pdf to a docx

My code:

$filePath = "C:\Users\Larso\Downloads\Install.pdf"
$wd = New-Object -ComObject Word.Application
$wd.Visible = $true
$txt = $wd.Documents.Open(
$filePath,
$false,
$false,
$false)

$wd.Documents[1].SaveAs("C:\Users\Larso\Downloads\Install.docx")
$wd.Documents[1].Close()

i get error:

New-Object : Retrieving the COM class factory for component with CLSID {00000000-0000-0000-0000-000000000000}

what did i do wrong or am missing?

2

Is Microsoft Word installed on the device that is running this code?

3

Yes it is, is it possible like excel, where i needed to download the module for it to work in powershell?

4

so i jsut tried

Get-Command | Where-Object -Property Name -Match ‘Word’

and i got

function Set-PcsvDeviceUserPassword

and

cmdlet Reset-ComputerMachinePassword

 

5

Now, one thing i also noticed was when i search WORD, it does list it under Apps.

No, Excel and Word use COM Objects, here are some more examples. These were mostly used as interfaces for scripting languages like VBScript because they could not access .NET framework.

While there are wrappers for Microsoft Word, like PSWriteWord, they typically still leverage the COM Object. The error you posted looks like Word is not installed, the COM Object is not registered or something is generally broken as your code to open Word does work on my system. If you run this, it should be True:

$comObjects = Get-ChildItem HKLM:\Software\Classes -ErrorAction SilentlyContinue | Where-Object {
   $_.PSChildName -match '^\w+\.\w+$' -and (Test-Path -Path "$($_.PSPath)\CLSID")
} | Select-Object -ExpandProperty PSChildName

$comObjects -contains 'Word.Application'

If it is not True, you may want to try another workstation or re-install\repair Office.

Ok, that test really helped. Unfortunately, it did come up as false, i was running it in Powershell ISE as an administrator. I tried the repair, uninstalled and reinstalled, and still kept getting False. What other work stations do you recommend?
