Thanks in advance for your help. I installed XAMPP 5.6.15, localhost on Microsoft Edge showed the welcome page but was not able to get a simple PHP script to run.
I have Windows 10 and got a message that UAC would not allow some aspects to work.
The script was:
echo "<h1>Hello World!</h1>"
Browser opens, closes, and shows me a download page for IE.
I would appreciate any suggestions.
