I'm having difficulty installing an extension...

Hi All,

I'm hoping that someone can help me with an extension issue, this is the first extension I've tried to install so I'm presuming that I'm doing something wrong.

I'm installing AnimDessin2 through the Adobe Exchange. It states that it is installed but it doesn't appear under extensions in Photoshop. I tried uninstalling and reinstalling but it isn't helping. I tried closing Photoshop down and restarting my MacBook but no luck there either. I don't see anything about extensions in the CC app, nor any notifications about anything downloading/installing.

I followed Adobe's instructions on downloading Anastasiy's Extension Manager but it doesn't appear there either. When I manually download the extension and try to install it, I get a message stating that an extension of that name is already installed and I need to uninstall it first. It doesn't appear in the list so I have no idea where to find it.

Like I said, it's probably just something I've missed and I'm hoping that someone can point me in the right direction.

Thanks

Shaun
