Windows 7 How to Migrate Files to a New User Profile After MSI Error 2203

I keep getting the 2203 Error regardring MSI and tried several fixes including MS Utility Cleaner. Unfortuatlety it won't allow me to install it even as admin. So, I read someone's post in another forum to create a new profile, bring over all my stuff then just delete the old profile. It seems to be valid cause I tried installing and uninstalling programs in another profile and had no problems. However where I read this, they didn't go into specifics as to how they brought everything over. Is it a matter of dragging Icons into the shared desktop then pull them into my new profile, and coping all my docs to shared folders?
Any help would be appreciated.
