How to Install

1) Unzip the downloaded file.
2) Copy the file "MOD_AAAUnlockAllDevelopmentPaths.dzip" into the "CookedPC" folder of your "The Witcher 2" base game folder. There's nothing
further to unzip - you're done. It won't overwrite any original file, since the original is in the pack0.dzip
archive.
3) Note the extension: You install the .dzip file, not the .zip file it comes in.

How to Uninstall

Delete the file "The Witcher 2CookedPCMOD_AAAUnlockAllDevelopmentPaths.dzip"

If you uninstall it, the development paths will be locked again if they're supposed to still be locked had you not used this mod. However, any abilities you've invested talent points in should remain learned even if they're now in a relocked branch (all sales final).
