You need to create a directory on your C: drive called :
CoffeeRoastingDB
(no spaces). Then unzip the file into that C:\CoffeeRoastingDB directory.
Start it by opening the file
CoffeeRoasting.mdb
If you still get problems or you already did this (sorry!), post again. If that solves the problem, what is happening is that there are TWO database files involved - the CoffeeRoasting.mdb file is the front end, the info you type in later is stored in the CoffeeRoasting_be.mdb file ("be" for "back end").
The first file (with the information entry screens) expects to find the second ("be") file in C:\CoffeeRoastingDB to store your information in - if it's not in that directory, you are stuck.
If you haven't already done so then you really need to look at the home page :
http://improbablystructuredlayers.net/CoffeeRoastingDB/CRDBHome.htm
for this DB. It isn't as complete as I would like but looking at the sections "Installation / Upgrade Instructions" and (once it is running OK) "Basic Workflow" is essential to avoid major confusion. It can be a bit confusing even after that!
I hope my post on the roasting forum might help a bit too. I sneaked it into a thread on Coffee Trails so you might not have noticed it, sorry about that - click here to see it 1/4 of the way down this page :
