Normally this wouldn\u2019t be blog-worthy but this time the installation threw up several headaches that I\u2019ve not encountered before, and one I had and should have known better!<\/p>\n

First, the schoolgirl error. Always make sure you run the Oracle Universal Installer with the Run as Administrator option. Frustratingly, if you don\u2019t Oracle doesn\u2019t immediately throw an error, but waits until you are at the point where it wants to write registry keys before informing you of a problem. At this point it has already done quite a bit of the configuration work so re-trying the install often fails if you simply try to rerun it. The only solution is to fully de-install Grid using this Oracle note:\u00a0https:\/\/docs.oracle.com\/database\/121\/CWLIN\/rem_orcl.htm#CWLIN350<\/strong><\/a>\u00a0and retry the install. Far from ideal.<\/p>\n

The second problem is one that plenty of people have hit, Oracle and Windows password complexity mismatch. This is a bug that I really cannot understand why Oracle haven\u2019t fixed yet, but perhaps it\u2019s more complex than I am giving them credit for. If whilst doing a software install you get an error during the installation window about \u2018Couldn\u2019t create Oracle home user\u2019 and you DEFINITELY ran the installer as Admin, then chances are you\u2019ve fallen foul of this. The issue is fully repeatable. All you need to do is:<\/p>\n
