Hi Frank,
Why did you install that package for your system? Did you encounter the issue in the article below?
Internet Explorer 11 crashes when you turn on or turn off Enterprise Mode in the Tools menu

If no, please uninstall it.
If yes, check the following settings:
1. Press WIN+R to open the Run window, type
SystemPropertiesAdvanced and press Enter.
2. Click the environment variables... button.
3. Find the path variable and check if c:\windows\system32 (or
%SystemRoot%\system32) is present between all the paths.
If not, add it at the end of the entire string (preceded by a semi colon) and click Always ok.
4. Check if you have got IERTUTIL.DLL in c:\windows\system32.
