When you click the Organize Favorites option under the Favorites menu in Internet Explorer, the following error occurs and the Organize Favorites dialog appears blank as in the graphic below:

An error has occurred in this dialog.

Invalid class string

This happens due to missing Microsoft JScript registration. And the fix is to register the DLL.

Windows XP

1. Login to an account that has administrative privileges.

2. Click Start, Run. Type the following command:

regsvr32 jscript.dll

3. Press {ENTER}

Windows Vista and Windows 7

1. Open an elevated Command Prompt window. To do so, click Start, click All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator.

2. Type the following command:

regsvr32 jscript.dll

3. Press {ENTER}

You should see the "DllRegisterServer in jscript.dll succeeded." message box.

Logoff and login back. See if you’re able to open the "Organize Favorites" dialog in Internet Explorer successfully.

    I was in need of help on this, and the fix described here worked just fine.
    The other fixes I came across seemed to involve Regedit and deleting the existing Favorites, which I couldn’t believe was necessary. Overkill.
    Nice work.

    Excellent! After months working with problems in my IE, this command line has fixed “JUST” everything! Thanks a lot!

    Thanks so much. The problem I was having was with MMC (Microsoft Management Console). After a long circuitous route to track down where the problem was on my system I happened to find that Organize Favorites was also not working properly, I ended up here, and it solved the MMC problem.
