This is the WinRaR - 4.65. The new version includes a patch to activate. 100% working. I am also using this version. Download the Zip file 2.00MB and install. Then apply the path. If the WinRar was not patched using your name use a unblacklisted key which you can find in the bottom of the patch. Enjoy and post your comments !
