In the Microsoft Windows Vista operating system, there is an Internet Explorer error that may occur in some X64 (also known as 64-bit) systems after certain updates are installed. This error is crippling as Internet Explorer will close immediately upon encountering the error. Luckily for Vista X64 users, there are two versions of Internet Explorer installed (with no noticeable differences), a 64-bit version and a 32-bit version, and the 32-bit version does not encounter this error. By changing the 64-bit Internet Explorer shortcut target to the path of the 32-bit Internet Explorer, users can successfully eliminate the error.
Right-click on the desired shortcut to your 64-bit Internet Explorer and select "Properties" from the context menu.
Click to open the "Shortcut" tab (if necessary), then delete the current file paths in the "Target" and "Start in" text fields.
Type the text "C:\Program Files (x86)\Internet Explorer\iexplore.exe" into the "Target" text field, then type " %HOMEDRIVE%%HOMEPATH%" into the "Start in" text field.
Click "Apply" then "OK" to save your changes. Double-click on the shortcut. Internet Explorer 32-bit will now launch in place of Internet Explorer 64-bit.
