During the installation process Individual and Standalone Pro users are asked whether the installation should be for Just Me or All Users, the only difference in either case is where the database is stored.

• Picking Just me means the database will be stored in the users appdata folder structure
• Picking All users means it will be stored inside c:\taxcalchub

Just me would be used if the machine was shared between users and you didn't want the other users to be able to see the data

All users would be used if the machine is shared but more than one user may want to use TaxCalc.

If a reinstallation is needed, users should make sure they choose the same option as they did previously.
