ERROR: The application failed to initialize properly (0xc0000135). Click on OK to terminate the application.

Windows will give you this error if you try to run any application that requires the ".NET Framework" to run, but your computer does not have ".NET Framework" installed. To fix it, just install the .NET Framework from Microsoft:

Several applications in the NeuroSky's MindWave product bundle (including MindWave Manager, App Central, etc) require ".NET Framework 3.5". The MindWave bundle's installer should already automatically install ".NET Framework 3.5" for you if your system doesn't have it.

Many Windows XP systems do not come with ".NET Framework 3.5" installed. Most Windows Vista and Windows 7 computers already have ".NET Framework 3.5" installed by default.

(Please note that there is also a ".NET Framework 4.0", which is different from 3.5. The 4.0 will NOT run applications designed for 3.5.).
