Download The Client

Step 1: Sign-Up (for new users)

Create an account so you can get statistics credit.

Step 2: Download (v25.11) - UPDATED July 25, 2009

Most users: Windows | Windows 64-bit

Win Service Install: Windows NT | Windows NT 64-bit (rare option -- you'd know if you need)

Haiku: Haiku GCC2 | Haiku GCC4

Step 3: Update prime.txt

In order to be given credit, you must update the prime.txt file. Replace or update the prime.txt in the directory you've extracted your client to by:

updating

V5UserID=louie

V5UserID=<your username>

Step 4: Run!

You should be able to connect and get work now. Be aware that the Mac OS X and Linux clients are both "silent" command line programs and will give very little screen output. You can "tail -f prime.log" or "tail -f results.txt" to see what the client is doing. Also, it may be helpful to setup scripts to start these clients on boot-up since only the Windows client currently has that option built-in.
