I am having problems when I save a Articulate Project after I have made changes in the audio editor, the software locks up. Articulate says it does not support 64 bit systems or 64 bit PowerPoint. I just spent an hour and 139 bucks to be told by Microsoft 64 bit systems can not run 32 bit PowerPoint. How do I fix this? I have windows 7 64 bit and 2010 office 64 bit. Microsoft says it only installs 32 bit and you have it, to change to 64 bit installed. Every thing I have says its 64 bit.
