<h2><strong>Common Causes of the Error</strong></h2>
<p><span style="font-weight: 400;">Understanding the root cause helps resolve the problem faster. Below are the most frequent reasons behind this issue.</span></p>
<h3><strong>1. Corrupted Backup File</strong></h3>
<p><span style="font-weight: 400;">If the backup file is damaged during download, transfer, or storage, QuickBooks cannot read it properly.</span></p>
<h3><strong>2. Incorrect File Format</strong></h3>
<p><span style="font-weight: 400;">QuickBooks Mac uses specific file formats. If a Windows backup file is restored directly on Mac without conversion, the error may occur.</span></p>
<h3><strong>3. Incomplete Backup Creation</strong></h3>
<p><span style="font-weight: 400;">Sometimes backups are interrupted due to system crashes, resulting in incomplete files.</span></p>
<h3><strong>4. Software Version Mismatch</strong></h3>
<p><span style="font-weight: 400;">Older QuickBooks versions may fail to recognize backups created in newer versions.</span></p>
<p><span style="font-weight: 400;">If you are unsure which cause applies to your case, you can call </span><strong>+1-888-912-0074</strong><span style="font-weight: 400;"> for expert troubleshooting.</span></p>
