Get-Hotfix InstalledOn property not returning hotfix installed Date and Time on Windows Server 2008 SP2 but works on Windows Server 2008 R2 SP1

Question

Hi,
      I am working on a validation script to get the list of hotfixes installed on Domain Controllers every month as part of our monthly DC patching process. I have been successful in getting these details for DC's with (Windows Server 2008
R2 SP1, Powershell v2.0) using the below command. 
Get-HotFix -cn $computer | Select-Object PSComputerName,HotFixID,Description,InstalledBy,InstalledOn | where InstalledOn -ge (Get-Date -Day 1 -Format d) | FT -AutoSize
I execute the above from a jump box with powershell v4.0 (Server 2008 R2)
However, when I try the same command from the jump box to query DC's with (Server 2008 SP2, powershell v2.0). It doesn't return the InstalledOn date and time. It was giving error for the InstalledOn property and hence I renamed it to $_.InstalledOn. Now
I don't get error but still no details displayed for InstalledOn property.
I tried using the below, as could see on few forums that this might resolve the issue. I also tried removing the "where" part but still no installation date returned. 
Get-HotFix -cn $computer | Select-Object HotFixID, Description, InstalledBy, @{l="InstalledOn";e={[DateTime]::Parse($_.psbase.properties["installedon"].value,$([System.Globalization.CultureInfo]::GetCultureInfo("en-US")))}}
| where {$_.InstalledOn -ge (Get-Date -Day 1 -Format d)} | FT -AutoSize
Have tried this locally on the 2008 SP2 DC but still not working. Please advise what is going wrong? 
Note: If I execute the below command locally on the 2008 SP2 DC, I am getting the InstalledOn output. However, when executed from the jump box with powershell v4.0 (Server 2008 R2) to query
the same 2008 SP2 DC, it just gives the prompt again without any error or output. This behavior is consistent for other 2008 SP2 DC's in the environment.
Get-HotFix -cn $computer | Select-Object HotfixID,Description,InstalledBy,InstalledOn | where {$_.InstalledOn -ge (Get-Date -Day 1 -Format d)} | FT -AutoSize

Hi jrv, I have already tried the Win32_QuickFixEngineering option, which doesn't work either. Apologies for not mentioning the workarounds that I have already tried.
Get-Hotfix seems to be just a wrapper for Win32_QuickFixEngineering as per the below article. (http://technet.microsoft.com/en-us/library/hh849836.aspx)
I have seen a mention of using the WU ActiveX control on few forums, but was too lazy to read it through.
After rigorous testing, it makes me realize that somewhere the Get-Hotfix dates formatting\comparison isn't working.
