Issue
Installing TAC Config on a PC that already has I/NET using MSDE SQL server installed.
Environment
PC that already has I/NET using MSDE SQL server installed
Cause
The installation will ask if SQL server is already installed. This can be confusing if it is previously installed for I/NET. Since a new instance is required, the correct procedure is to install new.
Resolution
When you install TAC config, the installation program will ask you if you want to install MSDE SQL server or "a Microsoft SQL server is already installed." You have to pick "Install MSDE SQL server..." even though you already have one instance of MSDE. TAC config will install a new instance of MSDE for Vista.
You should only pick “a Microsoft SQL server is already installed” if you have another (not MSDE) SQL server installed on the machine that you want to use for Vista.
