Compiling for 64bit still fails to the 2nd error (TransactionId not a member of CryptoNote), your workaround doesn't fix it (it does fix the 1st error but it becomes irrelevant when compiling for 64 bits).
Yes, for 64bit it's not needed. Use cmake to configure and build with Visual Studio or use QT Creator. You need to configure properly QT build system to use MSVC not MINGW then.
Try to add
#include "IWalletLegacy.h"
in SendFrame.h
Is it Ukrainian cryptocurrency?
It's not, cryptocurrency is international and borderless, it can only be made by programmers and enthusiasts of Ukrainian origin and start growing from specific location. But this one is by no any means official or connected with government or something like this.
