[vbox-dev] Using python API bindings on Windows

Ok, I've just noticed that there was already a thread on this topic earlier
this month (I joined the dev list later, so I did not see this mail). The
problem is that I am using 32 bit python on 64bit Win7. With 64bit Python
the problem disappears. So currently there is no way to connect to 64 bit
VBox from a 32 bit app (to get the console)? and what if I connect to a 32
bit VBox (on 32bit Win) from a 32 bit app, is this supposed to work?

> vm = machByName(vbox_mgr, "win64")
> snap = vm.findSnapshot("1")
> session = vbox_mgr.mgr.getSessionObject(vbox_mgr.vbox)
> vm.lockMachine(session, 2);
> # session.console == None here
> I've also tried to restore a snapshot using vboxshell frontend, and I get
> the same result:
> 'NoneType' object has no attribute 'restoreSnapshot'
> I've tried it on 4.3.12 and on 4.3.14 - same result.
> For a running VM the console object is there and everything works fine. I

> Is it a bug or is it a problem of my installation?
> Thanks in advance,
