Why do I get Error 1 when building applications

[yen78]

I'm creating an executable using the Labview 6.1 application builder but I get this error: Error 1 ocurred at Gsim Sintax Check.vi. I didn´t install the Simulation and Control toolkit I copied the vis I needed to use them.
What can I do?
Thanks

yen,
Do you get this error at build of the application or from the executable itself? Does the VI run in the development environment?

I would build the executable from the development machine that has the toolkit on it.
