Ok so I was wondering being a win32 user at the moment, I found information on this but its driving me mad! I got openemr working on win32 with the pre-setup package by apachefriends right but when I install apache/php4/mysql4.1 by myself which I was hoping to achieve, I used this link
Most of the install problems have to do with setting up the mysql permissions appropriately.
Make sure that your mysql server is running.
Make sure that you can connect to the server with the root user
mysql -u root -p
mysql>
The latest setup program seems to require that you enter a password for the openemr user though it isn’t used if you use the root password for the setup.
