Thank you! That's certainly the reason for the problem. It should check
for both variants to find the 2.8.x versions. However, I do not need to
test this any more, because I have switched to wxWidgets 3.0.2 in the
meantime.

This changelog describes the changes from 2.8.x to 3.0.2, so the
"_amd64" is correct for 2.8.12 and there is no installer bug.
