Im not on Vista either - its a hosting company running win2003 servers.  I have three 4.5 installations running with these guys fine since early this year. The web directories and access rights are fine - my install now starts OK and progresses through the permissions tests, these all check back OK. Then no matter which type of install I pick I always end with the same error - about access rights to LogFailures.xml.resources

We've already been through checking the root level web directory has the correct access rights, and I guesse the DNN install tells me that is OK by the fact it can create and delete files and folders in the test stage of the install.

So far no running 4.6.2.... and no enlightenment about how to get over this showstopper either...

Got it working in the end.

I found a few files get created early on when you start running setup, including dotnetnuke.config, if the install doesnt work first time and you end up adjusting the connection details or customErrors then its worth killing that file so next time you run the install afresh as far as the installer is concerned. I also deleted and re-created the DB.  I went with auto-install as prescribed by shelton and it seemed to go smoothly from there (thanks!)

Im running with UK hosts http//www.pipeten.com btw, 4.5.1 and 4.6.2 compatible with some amazing support staff - I've quizzed them on live-chat at midnight for instant results and 2 min call closure times, phenomenal.
