So I've read a bunch of threads and have seen a bunch of stuff for vista and dvddecrypter but nothing on this problem. When I click on the installation file I get this error:

NSIS Error

The installer you are trying to use is corrupted or incomplete. This could be the result of a damaged disk, a failed download or a virus.

You may want to contact the author of this installer to obtain a new copy.

It may be possible to skip this check using the /NCRC command line switch (NOT RECOMMENDED).

So I just got a laptop with vista for my deployment and I'm trying to get it ready and I can't get DVDDecrypter to work. I know it's not a virus and I've tried downloading the program again, using the installer file I used on my other computer with XP and no luck. I'm pretty sure it's not the file. I've also tried installing it using the XP SP2 mode emulator on Vista and I still get the same message. Any help or suggestions would be appreciated.
