Microsoft® Exchange Server 2007 setup cannot continue because it detected existing Microsoft Exchange database files in the target installation path.

Exchange 2007 setup requires that the target installation path be empty of Microsoft Exchange database files.

To resolve this issue, remove all existing files from target installation paths and then rerun setup.

To delete existing Exchange Server database files from the target installation path
  1. In My Computer or Windows Explorer, locate the target install path.

    By default, the database files are located in:
    <systemDrive>:\Program Files\Microsoft\Exchange Server\Mailbox\First Storage Group.
  2. Right-click the files to be removed, and then select Delete.

  3. At the Confirm File Delete dialog, click Yes.

  4. Repeat steps 2 and 3 for all files in the target install paths.
