Changing Interface Version
 

I have been trying to change the Interface Version in an addon I would like to start creating but cannot get past how to change it, I am using WoW UI Designer. I thank you in advance for the help.

The interface version is defined in the TOC file of the addon. Like
The toc file is stored in the addons root folder. It's named <addonname>.toc.
It is a simple text file and can be edited with any common editor.

Thank you, Thank you, Thank you. I would never have thought of going into the TOC file directly and changing it. I was over thinking it and trying to get the WoW UI Designer to do it for me.

**I hope this answer from Duugu helps others like myself in the future**

You should also be aware that WoW UI Designer is extremely outdated, and as such the code it produces may not always work in the current version of WoW. In the long run you'll be better off just learning how to write addons yourself.
