Re: WSUS 3 New Installation
It seems to me that you have got old WSUS 3 installed but the regkey HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Update Services\Server\Setup is gone. It is required for the installation process to find out to either you are doing an uninstallation or an upgradation which ever is necessary. You can try to use ARP in control panel to remove original WSUS installation and then leave DB and everything else that you want to leave behind, then you can reinstall with original WSUS version. You will then be able to recover the original WSUS with regkey that is all created.
Re: WSUS 3 New Installation
I have already removed the old WSUS and I think that the uninstallation deleted that reg key as well. Can anyone tell me how to restore the key or else create a new key manually? Thanks.
