QuickBooks Update Error 15242 can be a real headache, especially when you’re trying to process payroll. This error often points to issues with the QuickBooks Desktop installation or the Microsoft Windows Installer (MSI) service. When this happens, your payroll tax tables or program updates can’t install correctly, which can lead to outdated information and compliance problems.

Let’s dive into common reasons for this error and how to fix it:

Damaged QuickBooks Installation: Sometimes, the QuickBooks program files themselves can get corrupted, preventing updates.
Incorrect Folder Permissions: If the folders where QuickBooks stores its update files don’t have the right permissions, the update process can fail.
Issues with Windows Installer Service: The Windows Installer is crucial for many software operations, including QuickBooks updates. If it’s not working correctly, you’ll see errors.
Interference from Security Software: Antivirus or firewall programs can sometimes block QuickBooks from downloading or installing updates.

Step-by-Step Solutions to Fix Error 15242
Here’s how you can typically resolve QuickBooks Update Error 15242:

1. Run QuickBooks Desktop as Administrator
Right-clicking the QuickBooks icon and selecting “Run as administrator” can often resolve permission-related issues that cause update errors.

2. Check and Adjust Folder Permissions
Ensure that the “C:Program FilesCommon FilesIntuitQuickBooks” folder (or “C:Program Files (x86)Common FilesIntuitQuickBooks” on 64-bit systems) has full control permissions for all users. Incorrect permissions are a frequent cause of update failures.

3. Re-register Microsoft Windows Installer
Sometimes, the Windows Installer service needs a refresh.

Press Windows + R, type msiexec /unreg, and press Enter.

Then, press Windows + R again, type msiexec /regserver, and press Enter.

Restart your computer and try the update again.

4. Temporarily Disable Antivirus/Firewall
Before updating, try temporarily disabling your antivirus and firewall. Remember to re-enable them immediately after the update is complete. This helps determine if they’re interfering with the update process. Read More
