I cannot see any interfaces using Windows 7 64 bit and Wireshark 2.4.6

edit

Same problem. Downloaded 2.6.1 for Windows 7, 64-bit. Can't get any of my *.pcap files to open. Can't get wireshark to even open. Any tips?

Not being able to open a pcap file, or even getting Wireshark to start is a totally different problem to not being able to see interfaces. There are no mass reports of Wireshark not running on Win 7, so it seems as though something's up with your installation or environment.

Try the following recovery steps:

1. Reboot.
2. Uninstall Wireshark.
3. Reboot.
4. Confirm that Wireshark has been removed (usually it's in C:\Program Files\Wireshark, or C:\Program Files (x86)\Wireshark, but you mahve have installed it to another location). If it hasn't repeat from step 2.
5. Install Wireshark 2.6.1

Good to know. Thank you. Did that but still having problems getting Wireshark to start. Will wireshark start if my wireless network card isn't up to the task?

On start-up, Wireshark asks the capture driver (WinPcap or npcap or USBpcap) about the interfaces available on the host, and this is where things seem to go wrong for you.

If you uninstall the capture driver (WinPcap and\or npcap and\or USBPcap), you should at least be able to start up Wireshark, although you won't be able to capture. If you have it installed I would start with USBPcap.

Awesome! Took six times but got it up and running. Thank you for your help! You're both a gentleman and a scholar.
