<p>One of Windows Backup errors that you may experience while using Windows 7 is:</p>
<p>The backup was not successful.<br />
The error is: Windows Backup encountered a problem while determining additional locations of one of the users included in backup. (0x81000038)</p>
<p><!--more--></p>
<p>This error usually happens if you are using Windows 7 with Microsoft Office 2000.</p>
<p>If you want to make sure which .msi package is causing this behaviour, you can do the following:</p>
<p>Edit the Windows Backup Service to &#8220;<span style="color: #003366;">Allow service to interact with desktop</span>&#8220;. Restart the service afterwards.</p>
<p>You should be notified when Backup comes across the offending msi. Just clear the message and proceed.</p>
<p><span style="color: #339966;">Solution:<br />
</span>Copy the <span style="color: #003366;"><strong>DATA1.MSI</strong></span> from the Microsoft Office 2000 disk to the <span style="color: #003366;"><strong>C:\Windows\System32</strong></span> folder.</p>
<p>This should fix the 0x81000038 error.</p>
