Any ideas?
Yes, install Catalyst v11.11.
BTW, a yearly repost?...:
If you are just trying to use vanitygen, here's a Windows binary HOWTO:
Installation:- If GPU acceleration is desired, install ATI Drivers v11.10-v11.11 (with SDK 2.5) or latest Nvidia driver, test that OpenCL is working with GPU miner software. If drivers with SDK >2.5 have been installed, files may need to be manually removed.
- Download and unzip vanitygen-0.22-win.zip to it's own directory.
- To interact with the program, you need to open a terminal/shell/command prompt in the program's directory. In Windows Vista/Win7 Explorer, hold down the shift key on the keyboard while right-clicking the folder where vanitygen was extracted, and choose Open command window here.
- Test CPU operation. This command line will generate a Bitcoin addresses beginning with 1ABCD in around a minute or less:
>vanitygen 1ABCD - Test GPU operation. This command line will generate a Bitcoin addresses beginning with 1ABCDE in around a minute, using the first OpenCL device in your system:
>oclvanitygen -d 0 1ABCDE
OpenCL GPU device configuration:OpenCL is the language used for talking to a GPU, and is installed with the video card driver. If the above GPU command didn't run correctly, generating over 1Mkey/s, then you should examine your OpenCL configuration. Remove the -d 0 option ("use device #0") from the command line above and run it again, which will list available OpenCL devices. Here's mine:
>oclvanitygen 1ABCD
Available OpenCL platforms:
0: [Advanced Micro Devices, Inc.] AMD Accelerated Parallel Processing
0: [Advanced Micro Devices, Inc.] Juniper
1: [GenuineIntel] Intel(R) Core(TM)2 Quad CPU Q6600 @ 2.40GHzBoth a GPU and the system CPU are available in my system; on yours, the GPU may not be the first listed. "Juniper" is this AMD GPU's code name.
The first line is the platform number, the second two lines are the available devices under that platform. Change the -d 0 line in the example above to the GPU desired. If no GPU is shown, the video card driver or OpenCL is not installed properly. If you have multiple OpenCL SDKs or implementations installed, more than one platform may be shown, specify the correct one (e.g.
-p 1 for the second platform if shown.)
Example command lines (oclvanitygen, device 0, default platform):- Search for exact prefix 1ABCDE, keep searching after first match is found (-k):
>oclvanitygen -d 0 -k 1ABCDE - Search for prefix 1ABCDE in any combination of upper or lower case (-i):
>oclvanitygen -d 0 -i 1ABCDE - Search for ABCD anywhere in address (only supported on CPU vanitygen) (-r):
>vanitygen -r ABCD - Search for prefix 1ABCDE, use a seed file to make address generation more secure and random (-s):
>oclvanitygen -d 0 -s RandomSeedFile.txt 1ABCDE - Search for prefix 1ABCDE, keep searching after first match is found, and save all found address to a file:
>oclvanitygen -d 0 -k -o GeneratedAddresses.txt 1ABCDE - Search for many prefixes at once using a text file listing them (newline after each prefix including last):
>oclvanitygen -d 0 -k -f PrefixList.txt - Use all options above including case-insensitive search, and turn on verbose mode for more information:
>oclvanitygen -d 0 -v -i -k -f PrefixList.txt -o GeneratedAddresses.txt -s RandomSeedFile.txt
When specifying a case-sensitive address prefix on the command line or in a text file list, you must only use valid Base58 characters. This means you must only use lower-case i or o, and only upper-case L, or you will get an error.
- Bad: 1celeron, 1CELERON
- Good: 1ceLeron, 1CELERoN
I found an address, now what?Vanitygen finds an address that matches your search parameters, and provides the
private key for that address. The private key is never shown to you in the Bitcoin client; it is used behind the scenes, and is the secret part of your address that you should never give to anyone.
The mainline Bitcoin client does not have the ability to use private keys directly, but you can do other things to use bitcoins sent to your new address:
- In Bitcoin-qt: Help -> Debug window -> Console. Type importprivkey 5Jxxxxxxxxxxx "my vanity addr"
- Use the "redeem private key" option on MtGox, and input the private key you found. Any Bitcoins sent to the address will now be automatically withdrawn to your MtGox account. This is permanent, there is no option to remove or cancel a private key once it is added to your MtGox account,
- Use an alternate Bitcoin client, such as Armory, that has an "import private key" feature,
