Error 8 - On install.

When you get an Error 8 on install, check these four things:

1. Make sure the Temp directory located under your root directory has nothing in it.
2. Check the permissions in REGEDT32 and on the root directory of each partition; Administrator and System must have Full Control. See the Technical Article Permissions for the steps to handle this.
3. Check if you have a bad CD drive (if so, it is usually because it's dirty).
4. Check your account. The account from which you install and run Diskeeper must be a member of the Administrators group, but not a member of any other local groups such as Power Users, Backup Operators, and so on. It does not matter if the account is a member of any Domain groups such as Domain Administrators and Domain Users. If you make a change to the group membership of your account, log out and back in before installing Diskeeper.
