Abacus Primary Framework
Abacus is a Primary Maths Framework.
The original version on CDs can run into problems due to the fact that it installs a SQL server on the local machine but if you actually follow the instructions - then it will generally install fine on XP.
Abacus is not supported on Win7, but they will send you an updated Easiteach CD that will install on Win7 and then the main planner tool can be installed as long as you run the install as administrator and then follow the compatibility troubleshooting dialogs.
N.B One little caveat, if you install it and then rename the machine, their are reg entries under Harcourt Education that need changing to reflect the machine name changes.
Abacus is now sold as a completely online tool.
