APC PowerChute Network Shutdown for Hyper-V won't install

Hi, I have PCNS for Hyper V installed on three HyperV servers.  I have setup auto shutdowns when the UPS batteries run low.

This worked at the weekend during a power outage except for one of the HyperV servers.

I tried uninstalling the software because the PCNS webpage on the server wouldn't even load.

After uninstalling PCNS, I have tried reinstalling it but get the error-
"you must remove the currently installed version of powerchute network shutdown".

Server is Windows Server 2008 R2 with Hyper-V
Software is PowerChute Network Shutdown v2.2.5 for Hyper-V

I have confirmed there is no listing of the software in the servers programs listing and no PCNS server is running.

here is the resolution to issue:

You will need to perform some manual steps to complete the uninstallation of the previous version.

1.) Stop the PCNS service (if it still shows in the Services list and if it is still running.)
2.) Delete the whole installation directory
3.) Delete the following registry entries:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\PowerChute network shutdown v2.x.x
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\PowerChuteNetShut

Note that there is a newer version of PCNS for Hyper-V, you should download the latest version and use that instead of your old version. We have now made the software free.

Hi,

Have you tried to reboot the server in question, which would completely remove any services pending deletion. Alternatively, you run Ccleaner which will get rid of all temp files and orphaned registry files. That should get you up and running.

I must state when using Ccleaner, ensure you take a registry backup when prompted and seeing as this is a server it would be advisable to take a full server backup, to avoid data loss or a non bootable system.

Best of luck!
