Install ICO format/plugin in photoshop CC?

The Telegraphics.com plug-in (ICOFOrmat.8bi) does not work in Photoshop CC as of Jun-2014.

WORKAROUND:

The workaround is to save the images as PNG (16x16, 32x32, 48x48 and 64x64), then convert them at

IcoBundle

You may want to combine those icons, so it will scale gracefully in File Explorer.

To combine those ico files, use ICOBundle (download from http://telegraphics.com.au/sw/product/ICOBundle)
The syntax to combine the icons is:
icobundl.exe -o <output file> <input files separated with spaces> -

For example:
icobundl -o test.ico test16.ico test32.ico test48.ico test64.ico

Enjoy!

To anyone that stumbles onto this post I would like to assure you that the ICOFormat plugin is alive and kickin and works well within CC, you need to create a folder ( if its not there already ) called "File Formats" inside of your C:\Program Files\Adobe\Photoshop CC 2015\Plug-Ins\File Formats <----- drop the plug-in inside this folder

Just go the site - Telegraphics - Free plugins for Photoshop & Illustrator...and other software scroll down

I doubt anyone needs this but here is a link illustrating the install procedure    How to Save a Favicon in Photoshop CC - YouTube

It looks like you only mentioned how this can be done for Windows users. What will be the way(file path) for Mac users? Should we create the same File Formats folder in the Plug-ins folder of Photoshop CC located in Applications? I already tried that and it didn't work. Any help is appreciated.

Easy: Hard Drive/Applications/[Photoshop version]/Plug-ins

Be sure to use the correct capitalization. If it still does not work, the plugin might not be compatible with the latest version on Mac: the page does mention that the ICO plugin is compatible with ALL version of Photoshop for WIndows, but up to CS6 for Macs.

There is always iConvert icons

The ICO (Windows Icon) Format plugin for Mac CS5/CS6 seems to work here with photoshop cc 2015 on Mac OS X 10.11.2

I just opened the downloaded dmg file and dragged the ICOFormat plugin to /Applications/Adobe Photoshop CC 2015/Plug-ins

Does this work with 2018?

I've installed the old ICOFormat plugin, straight into the /Applications/Adobe Photoshop CC 2018/Plug-ins folder, and it works fine in CC 2018.
