In that archive invoicr.sql is included.
There is folder named cake in that archive which is empty.It contain
exe files so through mail it is not possible.
so replace "cake" folder with "biz-solution's"(given in class) cake folder.
If u don't have "biz-solution " then download "cake 1.2.6 " from cake
php official website and replace cake folder with downloaded folder.
that "cake" folder contain library which is used by that "invoicr"
application.
In case u feel any problem to run that application then "feel free to ask".
I hope every thing will be going fine with this application.
LOVE CAKE...
cheers!
