TL;DR - only tested on Windows 10. Got desired results.
- What are implications of setting uninstall.exe to run as Administrator on
other/older Windows platforms?
- If no change made to ExecutionLevel then uninstall should be changed to give
a better error message when it fails.
https://ask.wireshark.org/question/7526/mmdbresolveexe-could-not-be-removed/
If uninstall.exe is not "Run as administrator" it fails with an obtuse error
about mmdbresolve.
When Control Panel or Settings->Apps are used to uninstall, Windows does the
UAC popup and asks for permission.
Uninstall then runs fine if user selects ok to continue.
-------------------------------------------------------------------------------
The installer makes a request to run as Administrator causing Windows to pop up
the UAC question.
https://code.wireshark.org/review/gitweb?p=wireshark.git;a=blob;f=packaging/nsis/wireshark.nsi
"NSIS runs as Administrator ..."
The uninstaller is explicitly set to run in user mode which fails on the first
file deletion which happens to be mmdbresolve.exe.
I have tested a build with the line below commented out. When uninstall.exe is
run, it pops up UAC and if granted, uninstall runs ok.

RequestExecutionLevel: none|user|highest|admin
"Windows Vista/7 automatically identifies NSIS installers and decides
administrator privileges are required."
