If you're running Windows:
for Windows 10, open Settings, select Apps, and there should be an entry for Wireshark - select it, and click the "Uninstall" button;
for Windows 11, open Settings, select Apps, select Installed Apps, and there should be an entry for Wireshark from which you can select "Uninstall" if you click the "..." item.
(Those are the only two versions of Windows on which the 4.2.x releases of Wireshark run.)
If you're running macOS, the application is uninstalled by dragging it to the Trash; see the ask.wireshark.org question mentioned in a comment for directions on uninstalling any system changes.
If you're running some other operating system, you probably installed Wireshark from the OS's packaging mechanism (APT for Debian and Debian-based Linux distributions, RPM for Linux distribtions that use it, various other packaging mechanisms for other Linux distributions, *BSDs, etc.). Those should provide mechanisms for uninstalling.
What Operating System are you using?
E.g. on Windows there is a
uninstall-wireshark.exe
in the directory where Wireshark is installed.For Mac see https://ask.wireshark.org/question/14...
I'm using Windows 10. The uninstall folder containing uninstall-wireshark.exe was never installed with 4.2.6. Can someone upload that folder or explain how to manually extract it from Wireshark-4.2.6-x64.exe.
There IS no uninstall folder. If you insist on manually uninstalling by running the uninstaller, rather than by using Settings, as described in my answer, uninstall-wireshark.exe is installed in the top-level installation directory for Wireshark.
The windows uninstaller is looking for uninstall-wireshark.exe, which does not exist, so it errors.
Uninstall-Wireshark.exe is nowhere in C:\Program Files\Wireshark.
