xbmc.gui 5.15.00 not satisfied fix (tutorial)

[lovebug0706]

I ran into this issue dozens of times while trying to get this theme to work on Kodi, because i have a newer version. Im gonna post the solution here, so people know. If gade01 is reading this, please fix the config.

1. Open up the zip.
2. Open up addon.xml in a text editor.
3. Replace the version required for xbmc.gui from 5.15.00 to 5.17.00 or whatever version its on (you can find it by going to the Kodi github, and going to xbmc/addons/xbmc.gui/addons and seeing what version it displays) and save the addon file.
4. repackage the zip file, and continue on with installing the theme.

After that, you shouldn't have to worry about the xbmc.gui error anymore. Just got TetradUI on Kodi 21!
