[GNC] Installing 3.11 in Windows

[Stan Brown (using GC 2.6.19)]

After putting it off again and again, I'm finally ready to upgrade to a
more recent version.

1. I'm on 2.6.19 now. I know conventional advice is to upgrade to the
last minor version of each major version in turn. Do I really need to
upgrade to 2.6.21 before 3.11? If I really need to I will, but if it's
not necessary I'd just as soon save the time.

2. I'd like to have GC 2, 3, and 4 on my computer at the same time,
installed to different directories of course, so that I can compare
reports from those versions of my data file. But the Windows installer
of 3.11 doesn't seem to offer a way to set the installation directory.
Am I missing something, or will it truly install only to the default
directory?

3. If I'm planning to run GC in English only, can I safely un-tick the
"Translation Files" item in the installer?

I looked at <https://wiki.gnucash.org/wiki/Installation> but it didn't
help with #2 and #3. And <https://www.gnucash.org/docs.phtml> doesn't
have any documentation for 3.11 or any other 3.x.
