I have installed Chart 5 on a Windows 7 machine. When I try to start Chart, I get a driver error - how do I install the driver correctly?

PowerLab driver errors with Chart 5 on a Windows 7 machine are a known issue. Problems with Chart 5 on Windows 7 are probable since Chart 5 has not been tested on the Windows 7 platform, and as such there can be unexpected behavior or performance issues. 
It is recommended the user update to LabChart 8, which are fully tested compatible with Windows 7.
