.NET 2.0

To run the connectBlue Toolbox, .NET Framework v2.0 must be installed on your computer.
It can be downloaded from


The Toolbox can, by default, not be run over a network for .NET security reasons. To do this, the security level for the requested zone (e.g. local intranet) must be changed to "Full Trust". This can be done using an administrative program called Microsoft .NET Framework 2.0 Configuration. It is recommended that it is not changed without consulting your IT administrator.


When the Toolbox is run the first time it creates a Toolbox.ini file in the same directory as the Toolbox.exe file. If the user does not have full access to that directory, the file is not created. This means that the Toolbox will always be started with default settings and not the previously used settings.
