Hello,
I want to use P4Merge in unity PC version but I cannot choose p4merge in the list.
Unity->Preferences->General Tab. Had 3 drop downs available to me: External Script Editor, Image Application and File Diff Tool. For File Diff Tool, it had selected None, but when I hit that drop down to see my options None is all that was listed, so I couldn’t browse for DiffMerge.
I have installed p4merge with the common installer.
I am on Windows XP 64 bits.
