- Step 3: remove the WAMP folder (C:\WAMP). Getting a problem with wampmanager.exe, I had to reboot the computer before I was able to delete this file and the C:\WAMP directory.
- Step 4: regedit to search and delete wampapache and wampmysql services. Use Ctrl+F to find these services. Note, these where already deleted when I did an uninstall and reboot.
- Step 5: restart the computer
- Step 6: install new WAMP
  - WAMP asks for my default web browser, I just select C:\Program Files\Internet Explorer\iexplore.exe
