I'm running the latest Windows version (Version 3.0.1 (v3.0.1-0-gea351cd8). Unfortunately there appears to be some issue when viewing certain DOCSIS MAC Management messages which appear on an older version, say 2.6.6. I would like to install an be able to run both so when I encounter this issue - I can simply bring up the older version to view the frames that 3.0.1 and later have issues with. What's the best way to do this? I installed 3.0.1 with WinPcap Compatability mode not selected, i.e. npcap mode, so I should be OK there.

Any particular reason for using WinPcap mode? Currently it doesn't really make much difference, but in future it may do so, and I'd like to understand any reasons behind your choice.

I meant with WinPcap Compatability mode not selected. Here's what i have in my notes:

If compatability mode is not selected, Npcap is installed in a different location C:\Windows\System32\Npcap with a different service name npcap so that both drivers can coexist on the same system. In this case, applications which only know about WinPcap will continue using that, while other applications can choose to use the newer and faster Npcap driver instead.

OK, I understand.

Caveat: If this DOCSIS bug is not documented, you should add it to the bug database.

Using multiple Wireshark installations

Create a directory for alternative installations ( On Windows, I would use "C:\Users\[you]\wiresharks" and on *nix, ~/wiresharks ). Install any other editions of Wireshark to this directory and add a desktop icon that points to Wireshark.exe in the new installation location (would be C:\Users\<you>\wiresharks).

On *nix, you can add something like this to your ~/.bashrc:

alias wireshark266='/home/<usr>/wiresharks/wireshark2.6.6/wireshark'

depending on where the wireshark binary is. On Macos, you may need to link to ~/wiresharks/ instead.

...or it might not get fixed.
