Windows XP - Internet Explorer Script Error. Line 30 Character 7, Library Not Registered.

The error message appears whenever I try to open a webpage. I've tried running a registry cleaner, deleting a program that I thought was causing the problem and checking "Display a notification about every script error"

Hey DaveUU,
This could be attributed to various factors. Following the basic steps to optimize internet explorer(IE) should help you in getting rid of this error message.
Do you have the default IE that comes with XP or have upgraded your browser?
Depending on the version of Internet Explorer, the steps would vary. The methods given below is for IE 8. However, the steps are more or less the same for all the versions of IE.
Method 1: Clear cached data in Internet Explorer
To determine whether a performance issue or an error message is caused by corruption in the temporary Internet files or in other cached information that is used by Internet Explorer, you must clear cached data. To do this, follow these steps:
   1. Open Internet Explorer.
   2. Click Tools, and then click Delete Browsing History.
   3. In Delete Browsing History, click Delete All.
   4. Click to select the Also delete files and settings stored by add-ons check box, and then click OK. 
 Run IE and test. If the problem persists, go to Method 2.
Method 2: Run Internet Explorer in "No Add-Ons" mode
An error may occur if an add-on is damaged or if an add-on conflicts with Internet Explorer. To verify the same, run IE in no add-ons mode.

1. Go to Start Menu > Programs > Accessories > System Tools.
2. Click Internet Explorer (No Add-Ons). Internet Explorer opens without add-ons, toolbars, or plug-ins.
3. Test Internet Explorer to verify that it works correctly.
If no errors occur, the problem is caused by one of the add-ons that typically load together with Internet Explorer. In this case, use one of the following options.
Option 1: Reset Internet Explorer
Note: Please note that running this will reset all user-defined settings including those set by installed extensions, toolbars and other add-ons to IE Defaults. This includes all Security, Privacy and Zone settings. Also this will clear browsing history, delete all temporary Internet Files, cookies, form data and especially all stored passwords. Resetting Internet Explorer's settings is not reversible. After a reset, all previous settings are lost and cannot be recovered.
To reset Internet Explorer settings, click the Fix it from the link below.

Option 2: Use the Manage Add-ons tool to determine which add-on is causing the issue
1. Open Internet Explorer.
2. Click Tools, and then click Manage Add-ons.
3. On the Show drop-down menu, select All add-ons to display all add-ons that are installed on the computer.
4. For each item in this list, select the add-on, and then click Disable in the Information window.
5. When you have disabled all the items in this list, click OK.
6. Exit and then restart Internet Explorer.
7. If issues do not reoccur, repeat steps 1 through 3.
8. Click Enable for a single add-on.
9. Repeat steps 6 through 8 until you determine which add-on causes errors to occur.
Test and see how it goes.
