Hi, I have a guy who claimed to "use PackageMaker all the time" to create an installer for my software program for Mac several days ago. He sent me a zip file via dropbox, I downloaded it to my Window 7 computer, uploaded it to a Windows 2008 RT server, but when users downloaded it from my server the zip file contains corrupt files... of course not usable. Previously another individual created a dmg file for me using PackageMaker and I downloaded and uploaded it to the same server, users did not have a problem about the file corruption. I personally can't test it because I don't have a Mac handy. What could be going on? Thanks.
