How do I remove an old version of WinPcap?

Question

I can't display my reply under each comment. Here is my code...

Comment model

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Comment extends Model
{
    public function commentable()
    {
        return $this->morphTo();
    }

    public function user()
    {
        return $this->belongsTo('App\User');
    }

    public function comments()
    {
        return $this->morphMany('App\Comment', 'commentable');
    }
}

Post model

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Post extends Model
{
    protected $fillable = [
        'user_id', 'topic', 'body', 'category',
    ];

    public function user()
    {
        return $this->belongsTo('App\User');
    }

    public function comments()
    {
        return $this->morphMany('App\Comment', 'commentable');
    }
}

Comment controller

<?php

namespace App\Http\Controllers;

use App\Comment;
use App\Post;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Auth;

class CommentController extends Controller
{
    public function store(Request $request, $post)
    {
        $comment = new Comment;
        $comment->body = $request->body;
        $comment->user_id = Auth::user()->id;
        $post = Post::find($post);
        $post->comments()->save($comment);

        return back();
    }

    public function replyStore(Request $request, $comment)
    {
        $comment = new Comment;
        $comment->body = $request->body;
        $comment->user_id = Auth::user()->id;
        $comment = Comment::find($comment);
        $comment->comments()->save($comment);

        return back();
    }
}

Routes

Route::post('/comment/store/{post}', 'CommentController@store')->name('comment.add');
Route::post('/reply/store/{commentid}', 'CommentController@replyStore')->name('reply.add');

I have created the normal table with parent_id but I don't know how to display the replies for each comment. Please, anyone who can help me with this - I am stranded here and the error coming from the second controller function which is replystore() saying it doesn't recognize the comments() method. Please help me out to display the reply.

Solution 1

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.

Solution 2

I resolved this issue on Windows 7 x64 by:

1. opening a command prompt as administrator (Win+R > cmd > Enter)
2. navigate to \windows\syswow64
3. delete Packet.dll
4. reboot
5. Install new version of Winpcap

Solution 3

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

Why do you have a "Windows 8 include directory" in Win7?

[Ramhound]

Are you using Windows 7 or Windows 8? This is important information. Please remove any reference to the version of Windows your not using.

[CramerTV]

Karan, The Windows 8 include directory I mentioned is likely there due to using Visual Studio 2012 which has Windows 8 functionality. Ramhound, as noted in the first sentence - I am using Windows 7. As to why I mentioned it, I was trying to ensure everyone had as much information as possible. I was not trying to confuse anyone but I clearly did. Apologies. Do you have any suggestions I might try?

[CramerTV]

Thanks mdpc - rebooting is always good advice when finding strange problems but this time it has not helped. This is actually a very long standing problem for me. I first attempted using WinPcap (via Wireshark) 3 months ago and have simply been doing without it. I tried again yesterday with the same results but now I cannot just 'do without' anymore.

[CramerTV]

I found that solution on the web, though it said to delete the files but alas, it didn't work for me.

[CramerTV]

I did not receive an error when I deleted packet.dll. As I noted in the original post "According to the WinPcap FAQ I need to delete packet.* and wpcap.dll as well as npf.sys. Done." (and it didn't work)

[CramerTV]

As I noted in the question I deleted packet.* which included packet.dll. It didn't work for me. My situation may have been unique.

This fixed my issue as well - I had some crummy Netgear USB software still installed, and it blocked WinPcap... uninstalling made it work, thanks!

Use Process Explorer feature Find Handle or DLL to find the application that is using Packet.dll file. In my case it was same Netgear wifi USB adapter software.
