Simply, this is Fruityloops Studio 8.0 XXL edition.
It is a reupload of another torrent (I had the crack then they stopped seeding so I didnt have the setup file from there, but I did from another torrent), so I have made this torrent. The crack does work, I have tried it myself. Dont believe me? Try it yourself.
The crack consists of 2 files, a .reg file and a .dll file.
People have claimed the crack contains virii, so I have done an online scan:
FLEngine.dll: http://virusscan.jotti.org/en/scanresult/e93a675edbd27cb56c1ba935583f0d9b20ccd25f/a87337c6ee92a01c8668e9923d6d67d3f1761817
FLRegkey.reg: http://virusscan.jotti.org/en/scanresult/cf21acb654395418bcc441cd1bd3438b8d54b29a/cdd0dbd01f9d5fe2dce351ecc3e7a51ad0afcf06
As I have low quota, I have not scanned the setup file, but if you wish to scan for me it would be greatly appreciated.
Cracking instructions are in the readme.
