Adobe removed support for the Extension Manager in CC 2015. ZXPInstaller is an open source replacement that makes it easy to install extensions. This is the preferred installation method. Note: the term “Extension”, “Add-on”, “Panel”, and “Plug-in” are used interchangeably.

  2. Quit either Illustrator or Photoshop if they are open

    2. That’s normal, click Ok to continue.
  4. The Add-on: Purchase, download and uncompress the add-on if you have not already done so
  5. Drag the [The Name of the Add-on].zxp, e.g., TheRandomizer.zxp, file onto ZXPInstaller
  6. When ZXPInstaller says your installation is complete, your extension has been installed
  7. Restart Illustrator or Photoshop. You will find extension in the Window menu under Extensions / [The Name of the Add-on]

  • Purchase Confirmation page following your purchase.
  • If you didn’t save it, you should have received an email with the subject “Purchase Receipt” from “Created by Dr. Woohoo!” and/or “sales@drwoohoo.com” as well. Didn’t get the email, you can check your Junk email folder or…
  • Lastly, if you still can’t find the License Key, you can log in (Account > Login) to the Created by… Dr. Woohoo site and go to the menu Account > Purchase History. Login info:
    1. Your login info is typically your WordPress login info.
    2. Otherwise, you might have created a new one during the purchase process.
    3. Otherwise, an account was automatically created for you during the purchase process and would have received the account info via email following your purchase.

Tip: Workflow

Here are a few tips on workflows that work well:

  1. Select the Objects before you select the Swatches.
  2. Select the Objects on your Artboard and then click on the “Select Objects” button in add-on to link them.
  3. Select the Swatches in your Swatches Panel and then click on the “Select Swatches” button in the add-on to link them.

Tip: Start out small

When you are testing out some new random variations, select a smaller number of Objects. The number of selected Objects is relative to how fast your computer is, but you can try less than 100. After the objects are selected, select as many Swatches as you would like because they won’t slow things down in the same was as the Objects will. With the Objects and Swatches selected, go to the Randomize section and click on the Randomize Once button to test out the colors.

When you’re happy and confident about your color selection, select the larger number of Objects and proceed to either the Randomize or Batch sections.

Tip: Make sure the Fill Tool is above the Stroke Tool

In your Tools Panel, make sure the Fill Tool is activated, meaning it’s in the foreground and above the Stroke Tool as seen in this image. If the Stroke tool is in the foreground weird things or no magic will happen.

How do I use Illustrator’s Color Themes + Color Guides with The Randomizer?

This video walks you through a simple example of using a Color Theme to generate a larger series of swatches via Color Guides. The colors are then saved to the Swatches panel, linked in The Randomizer extension and randomly applied to the different paths on the artboard.
