I am tyring to upgrade to Win7 RC from Vista. When I run the installer, I get an error "Cannot access network resource" and get asked for a password. I have an admin account but enter my logon details but then get a further error saying "windows can't access "g:setup". I can access that disk drive fine normally and the installer works if it boot to it, but I want to do upgrade rather than clean install. I've also tried 'run as aadminstrator'- same error.

Hi AnthonyIs the system actually a part of a network?Let us know.Thank You for testing Windows 7 Ronnie Vernon MVP

It is a part of a home workgroup. Thanks for your fast reply.

Is anybody able to help with this- I've never had issues running installers from DVD/CD before now. any guidance much appreciated.
