I own MM9, and am considering upgrading to 2012. I am attempting to use the AHa!XLSimp add-in. I have loaded the add-ins for each version. Both load fine, and show up on the 'Add-Ins' menu under options in both products. Now what - and more importantly, where - do I find these to use them?! Do I have to somehow activate it or add it to a ribbon? I don't see an Add-In ribbon like in Microsoft products, so I'm pretty much at a dead end. In searching the internet, apparently I'm the only one who uses add-ins, or I'm missing something that is roaringly simple (probably the most likely option). Any help and direction would be appreciated.
