Can someone tell me what I am doing wrong with Get URL?

I have to finish this interactive CD today and I can't get my PC version to work. I have put

Get URL "pc\netscape\installer.exe"

to try to get it to run the installer when they click the install button. Nothing happens when I put it on the PC to test it...it SOUNDS like it's trying to do something, but it is only teasing me!

I've tried putting c: and c: file before it. Any suggestions?

Thanks!
