Instance GUID is improperly specified

Recently I was trying to install vCenter when I received the error "Instance GUID is improperly specified". This was a brand new Windows 2008 Server and a fresh install of vCenter, but the problem was that the install had failed a few times already due to other issues and rolled back. It seems that the rollback process does not completely clean up the files it creates, because one such file called 'instance.cfg' is created in c:\Program Data\VMware\VMware VirtualCenter and in it there is a line with the GUID. So to resolve this, simply delete that file and it will be recreated upon installation.

  1. Thank you - this was exactly what I needed. jointool-#.log isn't always accurate. Check status.txt for details about why Link Mode joins failed. If it is because of GUID or UUID issues, rename instance.cfg and try again - and it works!

    Again, thanks.
