Hi jcl, yes unpacking FXCM.zip solved the issue for the 32-bit. Zorro 2.50.2 starts and runs OK now, on my desktop computer.

I will not yet use the 64-bit Version and the C++ coding. Perhaps later.The advantages mentioned by AndrewAMD could be of a good use for me, when I progress more with my programming skills.

I am all set now with the new 2.50.2, thank you for the support.
