When you install inFlow, Microsoft SQL Server 2005 (backend database for inFlow) is installed during the process. If you’re having trouble installing you can solve the problem in one of two ways (as below) but first you should uninstall inFlow to ensure a clean, fresh installation. To do that, please follow the Clean Up guide here.
OPTION 1: Try installing SQL Server 2008 R2 instead
You may do so by:
1) Clicking Customize your installation
2) Checking to install SQL Server 2008
3) Choose Typical installation


OPTION 2: Run through the steps below to try to install SQL Server separately
Note: If you are running WINDOWS 8, please use these steps instead because SQL Server 2005 is not compatible with Windows 8.
1) Download SQL Server Express (with the language for your Windows) from Microsoft. [If you’re not sure which version it’s best to choose SQLEXPR.EXE from the list).
2) Install the downloaded file.
2a) Accept the licensing terms and then click next past the System Configuration Check (you can ignore any warnings here):




2b) Uncheck Hide advanced configuration options:

2c) Include the Connectivity Components in the database installation.
Select Will be installed on local hard drive:

2d) For Instance Name, select Named instance, and specify the name (all capitals): INFLOWSQL

Click next through the defaults for Service Account:

2e) For Authentication Mode, choose Mixed Authentication (or SQL Server Authentication).
For password, choose any password and write it down.

Click next to use the defaults through the Collation Settings, Configuration Options, and Error and Usage Report Settings, then click Install.




If you get any error messages when running this Microsoft SQL Server installer, try searching for solutions online.
3) If there are no errors or you’ve fixed them, the Microsoft SQL Server install is complete.
You should be able to continue to installing inFlow. Download inFlow from our website and install it.
Now that you’ve re-installed SQL Server you can run inFlow to re-attach the database OR if you’re installing for the first time then simply run the inFlow installer and it should recognize that you’ve already installed SQL Server and skip that step. Once the installation has been completed, or you’ve run the program it should prompt you to reset the database password, and in that case just set it to the one you used in Step 2e.
