However, this turned out to be a diversion, as my version of Home Premium already had SP1 pre-installed, so in fact there is nothing that can be done to un-install or re-install it. It also threw up an error code (which I read online) is usually associated with Service pack 1 not being properly installed. This looked promising, because the supplier went out of their way to emphasise this was a legitimate boxed version (origin Ireland) and was brand new.Īt first, windows appeared to accept the upgrade ke y, but then came up with the message 'Installation not successful'. I have been trying to upgrade my Sony Vaio Windows 7 laptop from Home Premium to Ultimate using a license-only upgrade key purchased off Amazon Uk.
Hello, hope this is a good place to post this.
