I too seem to have a problem getting to the admin part of this software.
And yes - I have tried `localhost/admin` & localhost/magento/admin (I always try new software on my own development machine).
And it doesn’t work - I get an error message (something about unexpected error 12263)
To be honest I’ve been developing/installing/testing softaware for almost twenty years and the the responses of some of the people on this website is nothing short of arrogant. The attitudes expressed on this, and several other forum threads I’ve come across, is that if you don’t understand you shouldn’t be here. And while, as this is a beta, it may to some extent be true - I do think some of the respondents could be a bit more civil.
On the face of it I like the product - although it does seem to be b***r to intsll - but I can;t stand the attitude of some of those on the forums as expressed in their response to simple queries.
