Can't pullout info from Regedit via Powershell - powershell

Question

I can't get this code to work:
Get-ChildItem hklm:\software\microsoft\windows\currentversion\uninstall | ForEach- Object {Get-ItemProperty $.pspath} |
Where-Object { $.DisplayName -Eq 'Microsoft Lync 2013'} | Select-Object DisplayVersion
What am i doing wrong?
This one works fine, both of them are in regedit, I am aware that this example is not en wow6432node, could that be the problem?
Get-ChildItem hklm:\software\microsoft\windows\currentversion\uninstall | ForEach-Object {Get-ItemProperty $.pspath} |
Where-Object { $.DisplayName -Eq 'Microsoft Security Client'} | Select-Object DisplayVersion

Answer 1

You had several syntax errors. In such cases, I try to resolve the one-liner into multiple steps and write a .ps1 file to spot the error(s). Copy this into a file of your choice:
$a = Get-ChildItem hklm:\software\microsoft\windows\currentversion\uninstall
$b = $a | ForEach-Object { Get-ItemProperty $_.pspath}
$c = $b | Where-Object { $_.DisplayName -Eq 'Microsoft Lync 2013'}
$d = $c | Select-Object DisplayVersion
write-host `$d.length $d.length
write-host content of `$d
$d
write-host
write-host intermediate results were:
write-host `$c.length $c.length
write-host `$b.length $b.length
write-host `$a.length $a.length
pause
I get no results left after step $c in my case, because I do not have Microsoft Lync 2013 installed:
PS> .\test.ps1
$d.length 0
content of $d
intermediate results were:
$c.length 0
$b.length 976
$a.length 992
