Emailing a Rev file

[Gabel Paul]

Hello everybody:

I made a .zip file from a standalone built for Mac OS X and emailed it  
to someone. It went through just fine. Then I did the same thing for a  
Windows build, but when I tried to email the file (7.9 MB) it bounced  
back with the following message:

Shouldn't this work either way? Any suggestions? Where do I find the  
"attachment guidelines"?

Thanks,
