 Hi,

Are you using the latest version of SuiteUSB? If not, can you please try out the CyAPI.lib from the respective folder, available as part of the latest SuiteUSB (http://www.cypress.com/?rID=34870). Please check and let us know, if this issue is seen with the latest version also.

 Hi,

Pleae try building the application by forcing that to x86 architecture in VS 2010 and see if it builds successfully?

 C# or C++ heavily depends on system performance counter. If the performance counter instantiation fails, then a exception is thrown by the system. Please try the following:

In the problem machine,launch performance monitor. Make sure the processor time graph is moving. To launch performance monitor, go to Run "perfmon.msc" and please make sure you can run performance monitoring successfully.

Thanks
