Opening the installer log, open in Internet Explorer.
Fix this!!
The installer log must be opened with the default browser.
I think it's about the 'How do you want to open this file' options, there are Windows Tutorials on how to change/remove/add/make default options.
It's not this
Agree, it opens in Chrome for me.
OP says is not this, but hasn't specified what exactly (probably won't agree with being marked correct).
