Solutions to Resolve QuickBooks Error 15105

Solution 1: Restart Your Computer

A simple restart can often resolve temporary system issues that might be stopping QuickBooks from updating. This can help clear minor system errors or processes that may be stuck and affecting QuickBooks.

1. Save any open work on your computer, and close all open applications, including QuickBooks, to avoid data loss.
2. Click on the Start menu (usually in the lower-left corner of your screen).
3. Choose Restart from the options (or Shut Down if you prefer to turn it off and then manually power it on again).
4. Wait for your computer to restart completely. Once it’s back on, open QuickBooks and try running the update again to see if the error is resolved.

Solution 2: Run QuickBooks as Administrator

Running QuickBooks with administrator privileges can help ensure it has full access to all necessary files and settings, which can resolve errors due to insufficient permissions.

1. Make sure QuickBooks is closed before starting.
2. Locate the QuickBooks icon on your desktop (or in your Start menu if not on the desktop).
3. Right-click the QuickBooks icon and select Run as Administrator from the options that appear.
4. If prompted by the User Account Control window, click Yes to allow QuickBooks to run with administrator permissions.
5. Once QuickBooks opens with these elevated permissions, try running the update again to see if it proceeds without errors.

Solution 3: Check Your Internet Connection

A strong and stable internet connection is crucial for downloading QuickBooks updates. Follow these steps to make sure your internet connection is ready for updates:

1. Restart Your Router or Modem: Unplug your router or modem, wait for about 10 seconds, then plug it back in. This can help reset the connection.
2. Disconnect Unnecessary Devices: If multiple devices are connected to the same network, disconnect those that aren’t in use to free up bandwidth, making the connection stronger for QuickBooks.
3. Run a Speed Test: Use an online speed test (like Speedtest.net) to check your internet speed. If your speed is too slow, it might cause update interruptions. If possible, switch to a wired connection (Ethernet cable) for a more stable connection.
4. Check Network Settings in QuickBooks: Go to Help > Internet Connection Setup within QuickBooks to make sure it’s set to use your internet connection for updates.

Solution 4: Temporarily Disable Antivirus or Firewall

Sometimes, antivirus software or firewall settings may mistakenly block QuickBooks from updating. Temporarily disabling them can help you identify if they’re causing the issue.

• Open your antivirus or firewall program from the system tray (usually found in the bottom-right corner of the screen).
• Look for an option that says Disable or Turn Off. Select it and choose a brief duration, like 10 or 15 minutes, just long enough to attempt the update.
• Open QuickBooks and try running the update again while your antivirus or firewall is disabled.
• After the update completes (or if it still doesn’t work), remember to re-enable your antivirus or firewall to keep your system protected.

Solution 5: Adjust User Account Control (UAC) Settings

User Account Control (UAC) settings can sometimes interfere with updates by restricting certain processes. Lowering these settings temporarily may help.

• Open the Control Panel by searching for it in the Start menu.
• Select User Accounts, then click User Account Control Settings.
• Move the slider to Never Notify to temporarily lower the settings.
• Click OK and restart your computer to apply the changes.
• Open QuickBooks and attempt the update. If it works, remember to reset the UAC settings to their previous level to keep your computer secure.

Solution 6: Temporarily Disable Firewall and Antivirus

Sometimes, your firewall or antivirus software may mistakenly block QuickBooks updates. Temporarily disabling them can allow the update to proceed smoothly.

• Open your computer’s Settings and navigate to Security or Firewall settings.
• Locate your Firewall and Antivirus settings and select the option to Turn Off or Disable them temporarily.
• Open QuickBooks and attempt the update again while the firewall and antivirus are disabled.
• Once the update is complete, remember to go back to your Security settings and Turn On the firewall and antivirus to keep your system protected.

Solution 7: Use QuickBooks File Doctor

QuickBooks File Doctor is a tool developed by Intuit to address various issues in QuickBooks, including corrupted files that might be causing QuickBooks Error Code 15105.
