I have a macro that batch converts drawing files to a variety of different formats.  I did not write the macro.  It worked fine on SW2010 x32 but in SW2010 x64 it just locks up SW.  I don't recieve an error code it just causes a lock up and I have to kill everything off with task scheduler.

I've attached the macro.

Does anyone know why it locks up in x64?  I'm on win7 by the way.

Thanks

Rob
