From http://lifeboat.com/ex/press.releases.bitcoins.hundred.thousand.dollars :

"to give back to the bitcoin community, Lifeboat Foundation has created the first Windows version of oclvanitygen in the world that runs well on high-end AMD cards. (Our version runs nearly four times as fast as the old version!) We also added support for compressed keys as well. You can download it for free at http://lifeboat.com/oclvanitygen and can learn more about what we did on GitHub at https://github.com/samr7/vanitygen/issues/19. oclvanitygen is used to create vanity bitcoin addresses such as our bitcoin address 1LifeboatVPg24QghZ73Dzrx8AxcJLCnoA that begins with 1Lifeboat. PGP signature for program is here."

Note that a high-end AMD card is defined as an AMD Radeon 7xxx GPU or greater. If you have a slower card then you can just download oclvanitygen as described at https://en.bitcoin.it/wiki/Vanitygen And if you need a Linux fix for high-end AMD cards, read https://github.com/samr7/vanitygen/issues/19 to learn how to fix oclvanitygen.

Finally, oclvanitygen, no matter what the operating system, hates the latest AMD Catalyst drivers. So if, for example, you are running Catalyst 13.9, you would also want to use the AMD APP SDK Runtime from Catalyst 12.10. (So all your Catalyst drivers would be brand new except for the SDK Runtime.)

Wow, impressive improvement!

Thanks! Maybe we will finally get a 1Lifeboat address from our high-end AMD card. We have been trying to get such an address for over 5 months —
most of the time with the original slow version of oclvanitygen.

Currently we have gotten 3 1Lifeboat addresses (in just 2 weeks!) from an ancient HP xw4400 workstation that was built in 2006. The trick being that it has a high-end NVIDIA card and also we got a bit lucky with it. (You want to try for more than 1Lifeboat address as some addresses look better than others. For example, our first 1Lifeboat address was 1LifeboatdUHD5eepYdcZZ57VjcwJU6CtB which could be read as 1Lifeboat, duh.)

It is my impression that only 7xxx's cause oclvanitygen problems. This is mostly due to development on oclvanitygen being halted 2 years ago so it was designed for the cards of the time. You should be able to download the regular version of oclvanitygen from https://en.bitcoin.it/wiki/Vanitygen and it should be fine. With 7xxx's you are forced to run the original version of oclvanitygen in slow mode which is *really* slow.

Try downloading the file http://lifeboat.com/oclvanitygen.zip

Let me know if this solves the problem. (This gives you pthreadVC2.dll and two more files plus oclvanitygen.exe)

A nice bitcoin address makes you look more professional so organizations like the Bitcoin Foundation use such addresses.

Also, as GPU bitcoin mining gets more difficult, this gives you a new way to use the power of your GPU that is bitcoin-related.

You can always compile your own version. Details are at https://github.com/samr7/vanitygen/issues/19

And hopefully you are encrypting your wallet.

Win7U 64Bit there

Are you sure that is the error message? I did a search and didn't find libeay31.dll on my machine. I did find libeay32.dll so I added it to the zip file at http://lifeboat.com/oclvanitygen (libeay32.dll is part of OpenSSL which *is* used by oclvanitygen.exe)
