QuickBooks Desktop is a powerful accounting software used by millions of businesses worldwide. While generally reliable, occasional errors can pop up, disrupting your workflow. One such error is the “QuickBooks Script Error: Unable to Get Property ‘Length’ of Undefined or Null Reference.” This can happen due to issues with Internet Explorer, corrupted data, or installation issues. This detailed guide will walk you through the causes of this error and provide step-by-step solutions to get you back on track.
Understanding the Error and Its Cause: When Scripts Go Wrong
This error message indicates a problem with a script, a small program that automates specific tasks within QuickBooks. The script itself is trying to access a variable or object, but that variable or object doesn’t exist (undefined) or is empty (null). This can happen due to various reasons, such as:
- Internet Explorer Issues: QuickBooks relies on Internet Explorer (IE) for some functionalities. If IE has scripting errors, compatibility issues, or outdated settings, it can affect scripts within QuickBooks.
- Corrupted Data or Installations: Damaged QuickBooks data files or a faulty installation can lead to script errors as well.
Fixing the Script Error
Let’s resolve the “QuickBooks Script Error: Unable to Get Property ‘Length’ of Undefined or Null Reference” error message. This seemingly cryptic message can leave you wondering what went wrong and How do I get rid of script errors in QuickBooks?
Here are several solutions you can try:
Solution 1: Reset Internet Explorer Settings
Since IE plays a role in QuickBooks scripting, resetting its settings can often resolve the issue. Here’s how:
- Close QuickBooks Desktop completely.
- Open Internet Explorer.
- Click on the Tools menu (gear icon in newer versions).
- Select Internet Options.
- In the Internet Options window, go to the Advanced tab.
- Click the Reset button.
- In the Reset Internet Explorer Settings window, check the box next to Delete personal settings (optional, but recommended for a more thorough reset).
- Click Reset again.
- Once the reset is complete, close Internet Explorer and restart your computer.
- Launch QuickBooks Desktop and check if the script error persists.
Solution 2: Make Internet Explorer Your Default Browser
QuickBooks might be trying to use a different browser than IE, causing script conflicts. Here’s how to set IE as the default:
- Close QuickBooks Desktop.
- Open Internet Explorer.
- Go to Tools (gear icon) > Internet Options.
- In the Internet Options window, go to the Programs tab.
- Click the Set defaults button.

Solution 3: Verify Date and Time Settings
Incorrect date and time settings can sometimes lead to unexpected behavior in software, including script errors. Here’s how to check them:

- Ensure your date, time, and time zone are set correctly. You can also choose to synchronize with an internet time server for automatic updates.

Solution 4: Repair QuickBooks Installation
If the previous solutions don’t work, a corrupted QuickBooks installation might be the culprit. Here’s how to repair it:
