Sitecore install errors

If you are running through the Sitecore installation wizard and at the instance name step get this error:
The name you entered is not unique
It is likely due to the fact that you have previously uninstalled a Sitecore instance with the same name. To fix this error (after first ensuring a Sitecore instance does not currently exist with the given name), you will need to:

  1. Open up the registry editor (regedit)
  2. Navigate to HKEY_LOCAL_MACHINE > SOFTWARE > Wow6432Node > Sitecore CMS
  3. Then select the child item (will have a GUID for a name) where the InstanceName value is equal to that which you are trying to install and right click delete
  4. Now restart the Sitecore installation wizard
If you then get to the IIS Web Site > Create a New Web Site step and get this error:
The site name must be unique.
 Then there may still be artifacts left over from the old Sitecore installation, ensure the following items have been removed/renamed:

  • IIS Application pool
  • IIS Web Site
  • Inetpub website root
  • SQL Server databases
Once these have all been removed you will need to restart the Sitecore installation wizard.

One final error which may occur is in relation the Sitecore installation wizard attaching the databases in SQL Server. If this error occurs, firstly ensure that the databases from the previous installations have been removed and then restart the server (the computer, not SQL Server instance).
