The easiest step is to start your Windows PC in safe mode and check if the updated WinPcap installer can remove the old one. That would indicate there is an background service on your computer that prevents you from installing a new version of WinPcap. This allows you to get rid of remaining files yourself, if the installer of the updated WinPcap software doesn't take care of that automagically. Because then all the processes are reset and as there is an incomplete version of the WinPcap on the system, no process will make use of this incomplete version anymore. Since you already uninstalled it, a full reboot of your PC is easier. This can be quite a labor-intensive way, depending on the amount of active processes on your computer. Once you are done with that, you can install the latest version of WinPcap. Close each process that uses any of the WinPcap. By double-clicking on a process you will see a tab that will give you information about which. It is probably easiest to look for the names of the WinPcap files that remain on your computer (perhaps: C:\Program Files (x86)\WinPcap) and using the excellent Process Explorer to see all currently active processes in your computer. dll files of the WinPcap software in use by another program. Nothing more, nothing less.īy uninstalling it, most of the installed WinPcap files are removed, but there is likely still one or more.

It only reports that the file is locked by at least one program. The error message doesn't specify which program because the file-system doesn't say which program locks the file.
