There are problems running 32bit Matlab on a 64bit system: http://www.mathworks.com/support/solutions/en/data/1-1CAT7/?solution=1-1CAT7 There are also some issues with CUDA, which we use a lot. I talked our support guys into reinstalling OS. So now I will have 32bit Windows and everything should wor...

Thank you, Chris, for the tip. It still did not work with Matlab. From what I understand WoW64 allows 32 bit apps to work in 64 bit environment and call 32 bit dlls. A 64 bit app (such as my copy of Matlab) still cannot call a 32 bit library. This did give me a hope that I might be able to write a 3...

Just realized that I never used usbtc08.dll directly out of my 64-bit Win 7 PC. Also found several post by Pico Tech reps that usbtc08.dll will only work in 32-bit environment. It should be CLEARLY listed in TC-08 specs that SDK is for 32-bit ONLY. At our university PC purchases are coming from the ...

What's weird is that everything worked fine before those Windows updates.

The code in usbtc08.h file:

#ifndef WIN32
#error Operating system not defined / supported
#endif

clearly prevents operation in 64-bit system, I have no idea why it worked before.

Any help?

Thank you

Sorry for posting it in the wrong category. Could moderators please move it to the Writing Your Own Software/C and C++.

Thank you
