The WinPcap project has ceased development and WinPcap and WinDump are no longer maintained. We recommend using Npcap instead.

If you do insist upon using WinPcap, be aware that its installer was built with an old version of NSIS and as a result is vulnerable to DLL hijacking.
For the list of changes, refer to the changelog.

When installing WinPcap 4.1.2 on Windows 7 I receive the following message
I've installed and uninstalled the program several times.
According to the WinPcap FAQ one should:
Delete packet.* (packet.dll, packet.lib, etc.)
Delete wpcap.dll
Internal Podalic Version
Delete npf.sys.
This was done and it still wouldn't install.
Additionally, I've removed the Network Packet Filter 'device' using the device manager.
I also did a search in the registry for winpcap with no results. I searched for wpcap and found only one entry - a header file in an include directory. I renamed it to .old with no success.
Further, I downloaded the source code and searched for part of the message above hoping to find how it checks for previous versions. That string (version of WinPcap) was not found in the source code (using grep in cygwin).
Finally, I emailed the two people who are listed as contacts for the program.
I also tried installing the program as an Administrator.
No luck. You all are my last hope. :)
The question is as above - I want to remove the old version of WinPcap. But other questions that could help me are, how does a program check for previous versions? Is there something else I should be searching for in the registry? Is there a way to find out which program is using winpcap? Is there a way to see if any programs have a dependency on winpcap? Any leads would be greatly appreciated.
Thanks!

I resolved this issue on Windows 7 x64 by:
- opening a command prompt as administrator (Win+R > cmd >Enter)
- navigate to
windowssyswow64
- delete
Packet.dll
- reboot
- Install new version of Winpcap

While I never found a way to remove the old WinpCap my colleague suggested I boot up in safe mode in order to stop the mystery program from using it. Although I still got a warning that an old version was unable to be removed (and do I want to continue with the install?) the installation this time was successful.
So if you find yourself in this dilemma a possible workaround is to boot up in safe mode and install from there.

When I uninstalled some Netgear Wireless Adapter software, packet.dll was removed, enabling me to successfully install WinPcap.

After the package removal, a reboot should be done before attempting to reinstall the package.

This worked for me.
Find and rename the following 2 files:
rename wpcap.dll to wpcap.dll.old
rename packet.dll to packet.dll.old
Try to reinstall WinpCap again.

as mentioned before, Packet.dll was being locked by another process.Windows 7 announces why it cannot be deleted when you try.Note which process has locked the dll and stop it (check Services and Processes)Remove the dll and restart the installation.

I had this problem running Win 7 x86. Attempted upgrade from v4.1.2 to v4.1.3.
I uninstalled v4.1.2 succesfully using vanilla MS uninstall
Using the earlier post for x64 users as a guide I navigated to the folder containing the file packet.dll. For x86 users it is located in windowssystem32 and attempted to delete that file.

If there is an application relying on the packet.dll file you will not be able to delete it. Not so bad because you should also get a message telling you which application(s) is currently using packet.dll
Take note of that application. Open task manager. Go to services. Find the Application. Right click and stop the service.
Now you can install WinPcap successfully. In my case I did not need to do a reboot.
Lastly in task manager, restart any services you stopped previously.
