When I tried to use "Programs and Features", the uninstall dialog popped a command window that was trying to call fing.exe with some uninstall flags, but this was just hanging. I could see the process using process explorer but couldn't stop it.
I eventually figured out (obvious in hindsight) that Fing installs an Overlook version of Winpcap that was preventing the uninstall. The steps that finally removed Fing from my PC were:
- Use "Programs and Features" to remove Overlook Winpcap
- Open Powershell as Admin
- Run "uninstall.exe" from the fing folder (something like "c:\program file (x86)\overlook.....")
Done.
