This is just to let everyone know about a problem I finally fixed.
After writing a small application using the C# interface and performing my tests, I took the same application, along with libFrontPanel-pinv.dll and libFrontPanel-csharp.dll to another computer. I kept getting an exception thrown when I tried to instantiate the front panel (FPGA = new okCFrontPanel();), the exception saying it couldn’t find the libFrontPanel-pinv.dll even though it was sitting in the same directory as my application executable.
Finally … I found that the redistributable components of VS2010 must be installed. On my first computer, I had installed everything, including the samples … which installed the required dlls. On the second computer I only installed the drivers and copied the two frontPanel dlls. Then I installed the c# API. No luck. Then I installed the C++ API. No luck. Then I installed the samples … which installed the required components.
