I got a chance to test on Win 10 (64).
Here are my comments:
Logged in as an unprivileged user, I right clicked on the MG installer, then chose "run as administrator".
After asking, the installer removed my previous installation of 3.12 as expected.
At the prompt asking if I want to visit the MG web site, I chose yes. That's when I ran into a nuisance-type problem; not an MG bug, but a Windows bug that could affect MG users installing MG.
This window popped up. You'll see from the screenshot that the "ok" button is greyed out. I clicked stuff, but couldn't get rid of it, or move to the side.
I had a couple prompts remaining to complete the installation. I clicked "yes" on one box, although I couldn't read what it said, because of the accursed window shown in the screenshot.
I managed to finish the installation, and start MG. The accursed window disappeared.
While changing a few MG options, the accursed window popped up again, and I couldn't close it.
I chose not to kill it from task manager, but instead, log out and back in again.
I couldn't find any MG shortcuts in my start menu; I navigated to the installation directory and started them from there. Did I miss a prompt during installation asking me if shortcuts should be added?
All 3 started for me.
I changed a few options. I set brightness to 2.00, saved, exited.
When I ran MG again, and arrived at the main menu, the brightness was as 2.00, but only for less than 1 second. It *visually* reverted back to the default. I went into options and saw that it was still set at 2.00, although *visually* it was at 1.00. On the brightness option, I clicked the right arrow and the brightness went to 2.10 as expected.
titi... don't ever make me boot to Windows again.
