If you use AutoCAD and have downloaded the new version of ADACX v4.2.1.0 (for ADAC v5.0.1) you will find the cuix files are not quite right and the ribbon has no tab for ADACX.

I have made fixes for this and the new file is available here -> https://www.adacx.com.au/sites/default/files/product_files/cui-files.zip

Simply close AutoCAD, unzip this file to the C:\ADACX\Support folder and restart AutoCAD and you should now have a fixed ribbon tab, you may have to right click on the ribbon area and 'show tabs' and select 'Add Ins' and the ADACX panel should now be visible on the Add Ins tab.

Sorry for any inconvenience, thanks.
