I have tried it and everything works as before, but with fewer warnings
Things that still don't work for me in combination with 64bit Windows is:
compiling with 32bit TheIDE a 64bit Application and start it with the debugger -> TheIDE crashes (the compiling and the application are working, just executing with the debugger crashes TheIDE)
compiling with 64bit TheIDE a 64bit Application and start it withe the debugger -> breakpoints don't really work
compiling with 64bit TheIDE a 32bit Application and start it with the debugger -> works as long as there are no breakpoints
