Unable to uninstall PCNS v2.2.3 from Hyper-V Windows 2008 R2

[Anonymous user]

Dear all

I need to install the PCNS v3.01 but to install it I need to uninstall the current installation which is at version 2.2.3 and is running on Hyper-V Windows Server 2008 R2 (Server Core i.e no GUI).

When I run cscript uninstall.vbs with administrator privileges nothing happens. Very strange. 

Has anyone encountered this before and how can I resolve it? Any help with this would be appreciated.

Thanks

Pierre

Hi,

Follow these instructions 

Please edit install.vbs and replace the subroutine IsRootUser()  - lines 253 to 288 - with the updated code below.

Sub IsRootUser ()
    Dim strUserName, strComputerName, strUserDomain, strAdminPath, objAdminInfo, strAdminPath2
    Dim objNetwork, objAdminGroup, objAdminGroup2
    Dim objWMIService, colAccounts, objAccount
    Dim bResult
    bResult = False
    
    Set objNetwork = CreateObject("Wscript.Network")
    strUserName = objNetwork.UserName
    strComputerName = objNetwork.ComputerName
    strUserDomain = objNetwork.UserDomain

    Set objWMIService = GetObject("winmgmts:\\" & strComputerName & "\root\cimv2")
    Set colAccounts = objWMIService.ExecQuery _
        ("Select * From Win32_Group Where Domain = '" & strComputerName & "' AND SID = 'S-1-5-32-544'")
If (strComputerName = strUserDomain) Then
    For Each objAccount In colAccounts
        strAdminPath = "WinNT://" & strComputerName & "/" & objAccount.Name
        Set objAdminGroup = GetObject(strAdminPath)
        If objAdminGroup.PropertyCount > 0 Then
            Dim strMem
            For Each strMem In objAdminGroup.Members
                If ( Lcase(strMem.Name) = LCase(strUserName) ) Then
                    bResult = True
                End If
            Next
        Else
            WScript.StdOut.WriteLine "[Error]: Connecting to the local Administrators group on " & strComputerName & " failed."
        End If
    Next
Else
    strAdminPath2 = "WinNT://" & strUserDomain & "/Domain Admins,group"
    Set objAdminGroup2 = GetObject(strAdminPath2)
    If objAdminGroup2.PropertyCount > 0 Then
        Dim strMem2
        For Each strMem2 In objAdminGroup2.Members

            If ( LCase(strMem2.Name) = LCase(strUserName) ) Then
                bResult = True
            End If
        Next
    Else
        WScript.StdOut.WriteLine "[Error]: Connecting to the Administrators group on Domain " & strUserDomain & " failed."
    End If

    If (bResult <> True) Then
        WScript.StdOut.WriteLine "[Error]: " & WScript.ScriptName & " must be run with administrator privileges!"
        CancelUninstallation
    End If
End If
    Set objNetwork = Nothing
    Set objAdminGroup = Nothing
End Sub

You should now be able to uninstall PCNS 2.2.3 on Windows 2008 Hyper-V Server Core.

Hi Bill

Thanks for your reply. I replaced the subroutine with the one you sent me and still the uninstall doesn't work. It says attempting to start script...... and does nothing.

Hi,

You will need to remove PCNS manually by editing the system registry. Please be aware that if you mistakenly edit a file not listed below you may cause the system to not run properly and it will need to be restored or rebuilt to correct the issue.

The steps below are base on the system being 64 bit.

1 - Stop PowerChute Service

From command prompt type net stop pcns1

2 - Open registry editor

From command prompt type c:\windows\regedit.exe

3 - Back up the registry

Once the registry editor is launched click on the Computer then go to file – export and save the file to a place where it can be access if it is needed to restore. 

4 – Click on HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\

Delete the APC folder

5 - Click on HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services

Delete the PCNS1 folder

6 - Click on HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall

Delete the PowerChute Network Shutdown folder

7 - Close the registry editor

8 – cd to C:\Program Files (x86)\

Delete the APC directory

9 - Reboot the system

10 - Install PCNS 4.1 it can be downloaded here http://www.apc.com/an/en/tools/download/software_comp.cfm?sw_sku=SFPCNS41-V

Hi Bill

Thanks for these detailed instructions. The reason I haven't installed PCNS 4.1 on our Hyper-V 2008 R2 servers was because I have the Hyper-V Powershell module absent from all our three servers. All I have present is the FailOverCluster Powershell module. I am now trying to find from where to find the Hyper-V PS module so as to install it on these servers and hopefully install PCNS 4.1 so as to properly shut down our Hyper-V hosts and Guest OS VMs in the event of a power failure.
