When using the desktop software, there are settings built into the operating system that can impact the software.   In Windows these settings will reside as part of Internet Explorer so while you may not typically use this browser it is important to have it updated and setup with the correct settings. 

If you are receiving a script error with the use of the desktop software then we recommend checking the following items:

1. If you have Internet Explorer 10 or earlier, you will need to update the browser to version 11. This can be done from the Microsoft website, with Windows Update or by searching the internet for "Internet Explorer."  The latest TaxAct edition requires at least Windows 7 and Internet Explorer 11 in order to function properly.
2. If you have Internet Explorer 11, try the following:
1. Open Internet Explorer and click Tools on the menu bar (press Alt on the keyboard to enable the toolbar if needed).
2. On the dropdown menu, click "Compatibility View settings."
3. If it's there, uncheck the box next to "Display all websites in Compatibility View."
4. Uncheck the box next to "Display intranet sites in Compatibility View."
3. If the above does not work you can try resetting your Internet Explorer security settings:
   1. Click Tools or the gear icon.
   2. Click Internet Options.
   3. Click the Security tab.
   4. Click "Reset all zones to the default level."

You can also try a complete reset of Internet Properties with the Reset button on the Advanced tab. Please note that this will change any custom settings and may have other effects that we cannot know or diagnose.

If you have Windows 10 with Microsoft Edge and are receiving these general script errors, Microsoft has information about intranets, using Internet Explorer as default and an "enterprise mode." Please consult Microsoft resources.
