Ah, thanks never read:
"Before you install phpBB 2 you need to create a Data Source Name or DSN. The exact way to do this will depend on your hosting provider, if you are unsure you should check with them before proceeding. In general though you should create a System DSN which points to the location where you have stored an unarchived copy of the ms_access_primer.mdb file (this is contained in the ms_access_primer.zip which can be found in install/schemas/). The name you give this DSN will be used during installation. Do not proceed until this step is complete!"
Works fine now, ty
