Vista - install issues

Hello,

I've just got a new macbook pro (running mac os x 10.5), and installed foldershare on it. When I start up the program, foldershare opens alright (the icon for it shows in the side bar and the gray version of the icon shows up in the system tray area). Then after about 15 seconds is just quits. There is no error message.

- I've uninstalled and reinstalled too many times to count hoping it will work by chance. I'm on a mac so the only uninstall I know how to do is basically drag the folder out of applications into the trash. maybe there is another way to more thoroughly uninstall?
- Possibly relevent information: when I first downloaded the install package, I opened it and started installing, but then I stopped because I wanted to figure out the name of my computer before I set it up.

If anyone can give me any help here I would really really appreciate it. I pretty much rely on this program everyday, so I'm totally bummed that something is preventing it from working on my new computer...

Thanks for help!

Ahh, someone from microsoft customer support helped me. If anyone is searching the posts and wants the answer: The problem was that i canceled the install on the first run, and I wasn't properly uninstalling the program:

if you want to properly uninstall foldershare on a mac, you have to delete

1) the foldershare application in /Applications/
2) the foldershare folder in /Library/Application Support
