The installation for ActiveReports for .NET 3.0 gives the user the option to install the program for everyone or the current user. If it is installed only for the current user, other users on the same machine will not be able to access it or use it.

If the installation was run while Visual Studio® was open, the help files will not be integrated until the user exits Visual Studio® and reopens it.

The most likely cause for this error is a permissions issue. Either the folder the setup is pointing to or the folder containing the setup files does not have the correct permissions. The user needs to verify that the system account for the local machine has permissions to the folder containing the setup and verify that the user installing the program has the appropriate permissions.
