Installing Inform and InSched
InSched version 26 (and earlier versions) uses SQL Server as its database engine, and requires Inform to be installed in order to work.
Updating InSched to Version 26
If a computer already has Inform and InSched installed, you can update it to the most current version 26 of InSched. If Inform and InSched are not yet installed on the computer, install them first — see Installing Inform and InSched.
