Thanks for your feedback so far in helping me to solve this problem. I am
running Windows 10. I do not get any sound indication of the screen asking me to
allow the program to make changes to my system. I get the dialog telling me to
wait while the setup is being prepared. Then I hear beeping for a few minutes.
During that time I alt-tab numerous times to make sure I’m not missing the
screen. Pretty much immediately after the beeping stops, I get what I’d describe
as a “clang” sound and a message telling me tht the installation has failed and
advising me to check the log bview.
Hopefully this provides some further clarification.
