I can't see all my installed fonts in the Datylon for Illustrator plug-in.

Installing Datylon for Illustrator with Adobe Illustrator open can cause font problems.

If you see no or only a few standard fonts in your Typeface list in the Datylon for Illustrator plug-in, it is likely that you installed the plug-in while Adobe Illustrator was still open. This can cause a conflict and prevent the plug-in from recognizing all the available fonts on your system. To resolve this issue, it is important to follow the steps below:

These are the steps to fix it:

3. Uninstall Illustrator
4. Install Illustrator
5. Install the plug-in (with the Illustrator closed)
