InstallShield 2012 Spring » InstallScript Language Reference

REGDB_KEYPATH_DOTNET_30 is a predefined constant whose value is the registry location (not including the root key) of the registry key for the RTM version of the .NET Framework 3.0. It is defined as follows:

Software\Microsoft\NET Framework Setup\NDP\v3.0\Setup\

Tip: You can use the REGDB_KEYPATH_DOTNET_30 variable to detect whether the RTM version of the .NET Framework 3.0 is installed. To detect whether SP1—or a later service pack—of the .NET Framework 3.0 is installed, use REGDB_KEYPATH_DOTNET_30_SP.

You cannot change the value of a predefined constant. You can use this constant to specify a key when calling a general registry-related function. This predefined constant is also supported when using the Is function.
