Download: http://pspinstaller.co.uk (Click PSPInstaller Adrenaline Edition in the top left).
PSPInstaller is a homebrew store for the PSP and has been going since October 2009. I will continue to support this for as long as there is interest. I'm thankful that people still use it. Works on Phats, Slims, Brite's and Go's as well as under Adrenaline.
Just drop it into your PSP/GAME folder and away you go!
Thanks!
