If you find the IE (Internet Explorer) will not install there are several things to try but I have found the most effective to be:
UNINSTALL THE CURRENT VERSION OF INTERNET EXPLORER:
- CONTROL PANEL > PROGRAMS AND FEATURES > on the top left click VIEW INSTALLED UPDATES
- Either find INTERNET EXPLORER or just perform a search (top right corner)
- Attempt to UNINSTALL the version you have
RUN SYSTEM FILE CHECKER:
- Run a CMD window using RUN AS ADMINISTRATOR
- type SFC /SCANNOW
- wait and reboot as directed
RUN THE MICROSOFT FIX IT TOOL:
- Run the Microsoft Internet Explorer Uninstall Repair Tool from HERE.
- Reboot as directed
- Read and follow the steps in UNINSTALL THE CURRENT VERSION OF IE above
- Reboot as directed
- Download the current Internet Explorer from Microsoft HERE and install it.
