Time is money, as well, when it comes to accounting and bookkeeping. Which is why programs like QuickBooks Desktop are so central to the infrastructure of most businesses.
It simplifies payroll, simplifies tax returns, tracks spending, and treats each penny like it's precious. And yet, even with such a great tool, even QuickBooks can sometimes run into technical difficulties.
One of the more tenacious—and confusing—issues that arise is QuickBooks Error 15242. This is a mistake that typically occurs while trying to update payroll or QuickBooks Desktop.
But what precisely is it, and why is it halting your workflow to a crashing halt? To the point: how do you fix it and prevent it from happening in the future?
This blog article breaks down QuickBooks Error 15242 in all its maddening gory detail, but still gives you clear, effective answers so you can get back to what's most important—running your business.
Understanding QuickBooks Error 15242
Let's start with the basics.
QuickBooks Error 15242 is specifically related to payroll and software updating. It's caused most frequently when QuickBooks is unable to authenticate a digital signature on its File Copy Service (FCS).
The FCS is needed during updating—it helps QuickBooks install downloaded updates correctly. When this service is disabled, corrupted, or not functioning properly, updating freezes, and the error code appears.
The message usually states:
Error 15242: The payroll update failed to finish. The QuickBooks FCS service is damaged or not running.
Now, that might sound geeky, but the root cause is almost always very simple to deal with.

Third-party antivirus or firewall blocking services.
All these causes can independently or collectively trigger error 15242.
The Real-World Impact of Error 15242
Error 15242 may seem like nothing more than just another technical inconvenience, but its impact can be crippling.
You may find yourself:

Step-by-Step Guide to Fixing QuickBooks Error 15242
With the "what" and the "why" out of the way, let's address the most important part—the fix.
Step 1: Check and Enable the QuickBooks File Copy Service (FCS)
Since FCS is the core of this mistake, ensuring it's running is your best protection.
Press Windows + R to open the Run dialog.
Type services.msc and hit Enter.
In the Services window, look for Intuit QuickBooks FCS.
Right-click on it and select Properties.
Change the Startup Type to Automatic or Manual.
Click Start to run the service.
Click Apply and then OK.
Then, try updating payroll again.
Step 2: Manually Update QuickBooks Desktop
Sometimes the error is caused by an outdated or partially downloaded update.
Open QuickBooks.
Click Help > Update QuickBooks Desktop.
Click the Update Now button.
Check the box next to Reset Update.
Click Get Updates.
Once updates are downloaded, restart QuickBooks and apply them.
Step 3: Check Payroll Subscription Status
Updates will not succeed if your payroll subscription is not valid or has expired.
Click Employees > My Payroll Service > Account/Billing Information.
Log in using your Intuit credentials.
Check your subscription status.
If timed out, renew and attempt the update again.
Step 4: QuickBooks Desktop Repair
Corruption within your QuickBooks software can be the culprit as well.
Close QuickBooks entirely.
Go to Control Panel > Programs and Features.
Find QuickBooks in the list, right-click, and choose Uninstall/Change.
Select Repair, then follow the on-screen instructions.
After finishing, restart your computer and open QuickBooks again.
Step 5: QuickBooks Tool Hub

Click Quick Fix My Program to fix any small issues.
Then, return to the Installation Issues tab and run the QuickBooks Install Diagnostic Tool.
The tools identify installation issues, system compatibility, and corrupted files.
Step 6: Modify User Account Control (UAC) Settings
Sometimes, UAC blocks QuickBooks from reaching basic system services.
Press Windows + S and type User Account Control Settings.
Drag the slider down to Never Notify.
Click OK and restart your computer.
Try updating payroll again. When it succeeds, you can go back to normal for UAC.
Step 7: Turn off Antivirus or Firewall Temporarily
Third-party antivirus applications and firewalls sometimes flag QuickBooks update files as threats.
Turn off your security software temporarily.
Try the payroll update.
Re-enable security software later and add exceptions to QuickBooks services.
