PowerShell Uninstall Error

I'm going to deploy 2003 SP2 on some servers. I want to uninstall PowerShell
and reinstall it after applying SP2. When I tried to uninstall PowerShell
via 'Add/Remove programs', I got this error message:

Uninstaller Error
An error occurred while trying to remove Hotfix for Windows Server 2003 (KB926139).

It may have already been uninstalled.
Would you like to remove Hotfix for Windows Server 2003 (KB926139) from the
Add or Remove programs list?

I clicked NO, then I launched PowerShell through its shortcut and it is still
alive and kickin'.
When I checked the windows directory I didn't find the uninstall files for
PowerShell ('$NtUninstallKB926139$').

What happens if I apply SP2 to the servers? Will I be able to install PowerShell
v2 when released without
uninstalling SP2 first?


Needless to say that this is very ANNOYING!. What if one forgets to remove
PowerShell prior to SP install.
Is he doomed to live with PowerShell v1? Removing SP from production servers
is not a trivial matter.

If I understand things correctly, PowerShell v1.0 is technically a hot fix.
If you install it prior to SP2 and then install SP2, you won't be able to
uninstall it. The recommended course was to uninstall PowerShell, install
SP2 and then reinstall PowerShell if you wanted to be able to uninstall it
later. We'll have to see what happens with v2.0. I'm assuming eventually
it will be able to upgrade an existing installation.

Thanks Jeffery

I'm aware of the uninstall process and its downsides that's why I tried
to uninstall PowerShell in the *official way* prior to installing W3K SP2.
What happend later was another thing. Clicking the uninstall in Add/Remove
raised an error... and the uninstall files
we're not present on windows directory, and still I can launch PowerShell.

So, I wonder.. how can I uninstall it now *officialy*? SP2 needs to be deployed
to that server..
don't know how much time can I wait.

Anyway, I was thinking to copy the '$NtUninstallKB926139$' directory from
another server and execute it on the other.
Not sure I want to do that

Sorry, I misunderstood your post. I missed that you had uninstalled
PowerShell prior to SP2. So now you have an SP1 server with PowerShell
installed. When you went to Add/Remove, Windows said it wasn't installed
but it really is? I might try reinstalling PowerShell and then trying to
uninstall it. Then you should be able to install SP2.

answer to your problem, as Jeffery said. But be aware of the
following:

You cannot install Windows PowerShell 1.0 if it is already installed.
To determine whether Windows PowerShell 1.0 is installed, locate the
Install registry entry in the following registry path:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Powershell\1\Install
If the value of the Install entry is 1, Windows PowerShell 1.0 is
installed. If the Install entry is not present, Windows PowerShell 1.0
is not installed.

So, maybe it's needed to modify registry entry before reinstallation.

Here's what I did:

1. Run powershell setup.
2. PowerShell cannot be installed, plz remove old version.
3. deleted powershell's registry keys and run setup again.
4. Setup runs and installs powershell.
5. Removing powershell from Add/remove, I get the same error:

Uninstaller Error
An error occurred while trying to remove Hotfix for Windows Server 2003 (KB926139).

It may have already been uninstalled.
Would you like to remove Hotfix for Windows Server 2003 (KB926139) from the
Add or Remove programs list?

Now '$NtUninstallKB926139$' do exist in windows directory but it contains
two files only:
1. PSCustomSetupUtil.exe
2. PSSetupNativeUtils.exe
